| 1 | Multiple-aged granitoids and related tungsten-tin mineralization in the Nanling Range, South China显示文摘The Nanling metallogenic belt in South China is characterized by well-developed tungsten-tin mineralization related to multiple-aged granitoids.This belt is one of the 5 key prospecting and exploration areas among the 19 important metallogenic targets in China.Important progress has been made in recent years in understanding the Nanling granitoids and associated mineralization,and this paper introduces the latest major findings as follows:(1)there exists a series of Caledonian,Indosinian,and Yanshanian W-Sn-bearing granites;(2)the Sn-bearing Yanshanian granites in the Nanling Range form an NE-SW trending aluminous A-type granite belt that stretches over 350 km.The granites typically belong to the magnetite series,and dioritic micro-granular enclaves with mingling features are very common;(3)the Early Yanshanian Sn-and W-bearing granites possess different petrological and geochemical features to each other:most Sn-bearing granites are metaluminous to weakly peraluminous biotite(hornblende)granites,with zircon Hf(t)values of ca.2 to 8,whereas most W-bearing granites are peraluminous two-mica granites or muscovite granites with Hf(t)values of ca.8 to 12;(4)based on the petrology and geochemistry of the W-Sn-bearing granites,mineralogical studies have shown that common minerals such as titanite,magnetite,and biotite may be used as indicators for discriminating the mineralizing potential of the Sn-bearing granites.Similarly,W-bearing minerals such as wolframite may indicate the mineralizing potential of the W-bearing granites.Future studies should be focused on examining the internal relationships between the multiple-aged granites in composite bodies,the metallogenic peculiarities of multiple-aged W-Sn-bearing granites,the links between melt evolution and highly evolved ore-bearing felsic dykes,and the connections between granite domes and mineralization. | CHEN Jun WANG RuCheng ZHU JinChu LU JianJun MA DongSheng | 2013 | Science China Earth Sciences2013，56，12： | 46 |
| 2 | Molecular subtyping and genomic profiling expand precision medicine in refractory metastatic triple-negative breast cancer:the FUTURE trial显示文摘Triple-negative breast cancer(TNBC)is a highly heterogeneous disease,and molecular subtyping may result in improved diagnostic precision and targeted therapies.Our previous study classified TNBCs into four subtypes with putative therapeutic targets.Here,we conducted the FUTURE trial(ClinicalTrials.gov identifer:NCT03805399),a phaseⅠb/Ⅱsubtyping-based and genomic biomarker-guided umbrella trial,to evaluate the efficacy of these targets.Patients with refractory metastatic TNBC were enrolled and stratifed by TNBC subtypes and genomic biomarkers,and assigned to one of these seven arms:(A)pyrotinib with capecitabine,(B)androgen receptor inhibitor with CDK4/6 inhibitor,(C)anti PD-1 with nab-paclitaxel,(D)PARP inhibitor included,(E)and(F)anti-VEGFR included,or(G)mTOR inhibitor with nab paclitaxel.The primary end point was the objective response rate(ORR).We enrolled 69 refractory metastatic TNBC patients with a median of three previous lines of therapy(range,1-8).Objective response was achieved in 20(29.0%,95%confidence interval(CI):18.7%-41.2%)of the 69 intention-to-treat(ITT)patients.Our results showed that immunotherapy(arm C),in particular,achieved the highest ORR(52.6%,95%CI:28.9%-75.6%)in the ITT population.Arm E demonstrated favorable ORR(26.1%,95%C:10.2%-48.4%in the ITT population)but with more high grade(23)adverse events.Somatic mutations of TOP2A and CD8 immunohistochemical score may have the potential to predict immunotherapy response in the immunomodulatory subtype of TNBC.In conclusion,the phaseⅠb/ⅡFUTURE trial suggested a new concept for TNBC treatment,demonstrating the clinical beneft of subtyping-based targeted therapy for refractory metastatic TNBC. | Yi-Zhou Jiang Yin Liu Yi Xiao Xin Hu Lin Jiang Wen-ia Zuo Ding Ma Jiahan Ding Xiaoyu Zhu Jianjun Zou Claire Verschraegen Daniel G.Stover Virginia Kaklamani Zhong-Hua Wang Zhi-Ming Shao | 2021 | Cell Research2021，31，2： | 37 |
| 3 | Seasonal variations and size distributions of water-soluble ions in atmospheric aerosols in Beijing, 2012显示文摘The characteristics of water-soluble ions in airborne particulate matter in Beijing were investigated using ion chromatography. The results showed that the total concentrations of ions were 83.7 ± 48.9 μg/m3 in spring, 54.0 ± 17.0 μg/m3 in summer, 54.1 ± 42.9 μg/m3 in autumn, and 88.8 ± 47.7 μg/m3 in winter, respectively. Furthermore, out of all the ions, NO3-,SO42-and NH4+accounted for 81.2% in spring, 78.5% in summer, 74.6% in autumn, and 76.3%in winter. Mg2+and Ca2+were mainly associated with coarse particles, with a peak that ranged from 5.8 to 9.0 μm. Na+, NH4+and Cl-had a multi-mode distribution with peaks that ranged from 0.43 to 1.1 μm and 4.7 to 9.0 μm. K+, NO3-, and SO42-were mainly associated with fine particles, with a peak that ranged from 0.65 to 2.1 μm. The concentrations of Na+, K+,Mg2+, Ca2+, NH4+, Cl-, NO3-and SO42-were 2.69, 2.32, 1.01, 4.84, 16.9, 11.8, 42.0, and 44.1 μg/m3 in particulate matter(PM) on foggy days, respectively, which were 1.4 to 7.3 times higher than those on clear days. The concentrations of these ions were 2.40, 1.66, 0.92, 4.95, 17.5,7.00, 32.6, and 34.7 μg/m3 in PM on hazy days, respectively, which were 1.2–5.7 times higher than those on clear days. | Yongjie Yang Rui Zhou Jianjun Wu Yue Yu Zhiqiang Ma Lejian Zhang Yi'an Di | 2015 | Journal of Environmental Sciences2015，27，8： | 19 |
| 4 | Effect of Gastrodin on Early Brain Injury and Neurological Outcome After Subarachnoid Hemorrhage in Rats显示文摘Gastrodin is a phenolic glycoside that has been demonstrated to provide neuroprotection in preclinical models of central nervous system disease, but its effect in subarachnoid hemorrhage(SAH) remains unclear. In this study, we showed that intraperitoneal administration of gastrodin(100 mg/kg per day) significantly attenuated the SAH-induced neurological deficit, brain edema, and increased blood-brain barrier permeability in rats. Meanwhile, gastrodin treatment significantly reduced the SAHinduced elevation of glutamate concentration in the cerebrospinal fluid and the intracellular Ca2+ overload.Moreover, gastrodin suppressed the SAH-induced microglial activation, astrocyte activation, and neuronal apoptosis. Mechanistically, gastrodin significantly reduced the oxidative stress and inflammatory response, up-regulated the expression of nuclear factor erythroid 2–related factor2, heme oxygenase-1, phospho-Akt and B-cell lymphoma2, and down-regulated the expression of BCL2-associated X protein and cleaved caspase-3. Our results suggested that the administration of gastrodin provides neuroprotection against early brain injury after experimental SAH. | Xinzhi Wang Shuyue Li Jinbang Ma Chuangang Wang Anzhong Chen Zhenxue Xin Jianjun Zhang | 2019 | Neuroscience Bulletin2019，35，3： | 15 |
| 5 | Effects of particle composition and environmental parameters on catalytic hydrodechlorination of trichloroethylene by nanoscale bimetallic Ni-Fe显示文摘Catalytic nickel was successfully incorporated into nanoscale iron to enhance its dechlorination efficiency for trichloroethylene(TCE), one of the most commonly detected chlorinated organic compounds in groundwater. Ethane was the predominant product. The greatest dechlorination efficiency was achieved at 22 molar percent of nickel. This nanoscale Ni-Fe is poorly ordered and inhomogeneous; iron dissolution occurred whereas nickel was relatively stable during the 24-hr reaction. The morphological characterization provided significant new insights on the mechanism of catalytic hydrodechlorination by bimetallic nanoparticles. TCE degradation and ethane production rates were greatly affected by environmental parameters such as solution pH, temperature and common groundwater ions. Both rate constants decreased and then increased over the pH range of 6.5 to 8.0, with the minimum value occurring at pH 7.5. TCE degradation rate constant showed an increasing trend over the temperature range of 10 to 25?C. However, ethane production rate constant increased and then decreased over the range, with the maximum value occurring at 20?C. Most salts in the solution appeared to enhance the reaction in the first half hour but overall they displayed an inhibitory effect. Combined ions showed a similar effect as individual salts. | Jianjun Wei Yajing Qian Wenjuan Liu Lutao Wang Yijie Ge Jianghao Zhang Jiang Yu Xingmao Ma | 2014 | Journal of Environmental Sciences2014，26，5： | 9 |
| 6 | Neural stem cell transplantation with Nogo-66 receptor gene silencing to treat severe traumatic brain injury显示文摘Inhibition of neurite growth, which is mediated by the Nogo-66 receptor (NgR), affects nerve regeneration following neural stem cell (NSC) transplantation. The present study utilized RNA interference to silence NgR gene expression in NSCs, which were subsequently transplanted into rats with traumatic brain injury. Following transplantation of NSCs transfected with small interfering RNA, typical neural cell-like morphology was detected in injured brain tissues, and was accompanied by absence of brain tissue cavity, increased growth-associated protein 43 mRNA and protein expression, and improved neurological function compared with NSC transplantation alone. Results demonstrated that NSC transplantation with silenced NgR gene promoted functional recovery following brain injury. | Dong Wang Jianjun Zhang Jingjian Ma Yuan Mu Yinghui Zhuang | 2011 | Neural Regeneration Research2011，6，10： | 9 |
| 7 | Petrogenetic differences between the Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range,South China: A case study of the Tongshanling and Weijia deposits in southern Hunan Province显示文摘The Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range have distinctly different mineralogical and geochemical signatures. The Cu-Pb-Zn-bearing granites are dominated by metaluminous amphibole-bearing granodiorites, which have higher CaO/(Na2O+K2O) ratios, light/heavy rare earth element(LREE/HREE) ratios, and δEu values,lower Rb/Sr ratios, and weak Ba, Sr, P, and Ti depletions, exhibiting low degrees of fractionation. The W-bearing granites are highly differentiated and peraluminous, and they have lower CaO/(Na2O+K2O) ratios, LREE/HREE ratios, and δEu values,higher Rb/Sr ratios, and strong Ba, Sr, P, and Ti depletions. The Cu-Pb-Zn-bearing granites were formed predominantly between155.2 and 167.0 Ma with a peak value of 160.6 Ma, whereas the W-bearing granites were formed mainly from 151.1 to 161.8Ma with a peak value of 155.5 Ma. There is a time gap of about 5 Ma between the two different types of ore-bearing granites.Based on detailed geochronological and geochemical studies of both the Tongshanling Cu-Pb-Zn-bearing and Weijia W-bearing granites in southern Hunan Province and combined with the other Middle-Late Jurassic Cu-Pb-Zn-bearing and W-bearing granites in the Nanling Range, a genetic model of the two different types of ore-bearing granites has been proposed. Asthenosphere upwelling and basaltic magma underplating were induced by the subduction of the palaeo-Pacific plate. The underplated basaltic magmas provided heat to cause a partial melting of the mafic amphibolitic basement in the lower crust, resulting in the formation of Cu-Pb-Zn mineralization related granodioritic magmas. With the development of basaltic magma underplating,the muscovite-rich metasedimentary basement in the upper-middle crust was partially melted to generate W-bearing granitic magmas. The compositional difference of granite sources accounted for the metallogenic specialization, and the non-simultaneous partial melting of one source followed by the other brought about a time gap of about 5 Ma between the Cu-Pb-Zn-bearing and W-bearing granites. | HUANG XuDong LU JianJun Stanislas SIZARET WANG RuCheng MA DongSheng ZHANG RongQing ZHAO Xu WU JinWei | 2017 | Science China Earth Sciences2017，60，7： | 9 |
| 8 | Magnetic properties and large magnetocaloric effects of GdPd intermetallic compound显示文摘With the intention to explore excellent magnetocaloric materials, the intermetallic compound GdPd was synthesized by arc melting and heat treatment. The microstructure, magnetic and magnetocaloric properties of the intermetallic compound of GdPd were investigated by X-ray diffraction(XRD), scanning electron microscopy(SEM) and the physical property measurement system(PPMS). A large reversible magnetocaloric effect is observed in GdPd accompanied by a second order magnetic phase transition from paramagnetism to ferromagnetism at ~39 K. The paramagnetic Curie temperature(θp) and the effective magnetic moment(μ_(eff))are determined to be 34.7 K and 8.12 μ_B/Gd,respectively. The maximum entropy change(|△S_M^(Max)|) and the relative cooling power(RCP) under a field change of 5 T are estimated to be 20.14 J/(kg·K) and 433 J/kg, respectively. The giant reversible magnetocaloric effects(both the large△S_M and the high RCP) together with the absence of thermal and field hysteresis make the GdPd compound an attractive candidate for low-temperature magnetic refrigeration. | Jianjun Huo Yusong Du Gang Cheng Xiaofei Wu Lei Ma Jiang Wang Zhengcai Xia Guanghui Rao | 2018 | Journal of Rare Earths2018，36，10： | 8 |
| 9 | Retrieval and Analysis of Coal Fire Temperature in Wuda Coalfield, Inner Mongolia, China显示文摘Coal fire burning around the world is an environmental catastrophe characterized by the emission of noxious gases, particulate matter, and condensation by-products. In this study, coal fire temperature is retrieved based on Landsat 5 TM images and Generalized Single-Channel Algorithm (GSCA), in Wuda coalfield, Inner Mongolia, China. Then coal fire zones are extracted by Jenks′ natural breaks and threshold methods based on temperature images. Changes of coal fire zones are analyzed from 1989 to 2008. The results are summarized as follows: 1) The coal fire temperature retrieval method based on Landsat 5 TM and the GSCA model is effective and feasible, because the temperature error is relatively small (from –2.9℃ to +2.6℃) between the measured temperature and the retrieved temperature. 2) The accuracy is relatively high to extract coal fire zones through the Jenks′ natural breaks and threshold methods, because 83.56% of surveyed area is located in the coal fire zones extracted in 2005. 3) The coal fire area increased 9.81 × 10 5 m 2 from 1989 to 2005, and the annual growth is about 6.1 × 10 4 m 2 , with an annual increasing rate of 2.48%. The area of coal fire decreased by 8.1 × 10 5 m 2 from 2005 to 2008. | JIANG Weiguo ZHU Xiaohua WU Jianjun GU Lei MA Guobin LIU Xiaochen | 2011 | Chinese Geographical Science2011，21，2： | 7 |
| 10 | Preparation and hydrogen gas sensitive characteristics of highly ordered titania nanotube arrays显示文摘In this paper, we report the growth and characteristics of titania nanotube arrays prepared by anodic oxidation and then annealed in an oxygen atmosphere at 500℃. The titania nanotube arrays presented high sensitivity to hydrogen gas. The crystalline phase of the samples was checked by X-ray diffraction (XRD). The differences in the nanotubes morphology attributed to the etched samples due to anodiza- tion potential, reaction time and the electrolyte concentration were analyzed by scanning electron mi- croscopy (SEM). The gas sensitive parameters of the samples were obtained from resistance, the re- sponse time and the recovery time at different temperatures. | JI HuiMing LU HuiXiang MA DongFang YU JianJun MA ShiCai | 2008 | Chinese Science Bulletin2008，53，9： | 7 |
| 11 | Co-seismic Faults and Geological Hazards and Incidence of Active Fault of Wenchuan Ms 8.0 Earthquake,Sichuan,China显示文摘There are two co-seismic faults which developed when the Wenchuan earthquake happened. One occurred along the active fault zone in the central Longmen Mts.and the other in the front of Longmen Mts.The length of which is more than 270 km and about 80 km respectively.The co-seismic fault shows a reverse flexure belt with strike of N45°-60°E in the ground,which caused uplift at its northwest side and subsidence at the southeast.The fault face dips to the northwest with a dip angle ranging from 50°to 60°.The vertical offset of the co-seismic fault ranges 2.5-3.0 m along the Yingxiu-Beichuan co-seismic fault,and 1.5-1.1 m along the Doujiangyan-Hanwang fault.Movement of the coseismic fault presents obvious segmented features along the active fault zone in central Longmen Mts. For instance,in the section from Yingxiu to Leigu town,thrust without evident slip occurred;while from Beichuan to Qingchuan,thrust and dextral strike-slip take place.Main movement along the front Longmen Mts.shows thrust without slip and segmented features.The area of earthquake intensity more thanⅨdegree and the distribution of secondary geological hazards occurred along the hanging wall of co-seismic faults,and were consistent with the area of aftershock,and its width is less than 40km from co-seismic faults in the hanging wall.The secondary geological hazards,collapses,landslides, debris flows et al.,concentrated in the hanging wall of co-seismic fault within 0-20 km from co-seismic fault. | MA Yinsheng LONG Changxing TAN Chengxuan WANG Tao GONG Mingquan LIAO Chunting WU Manlu SHI Wei DU Jianjun PAN Feng | 2009 | Acta Geologica Sinica(English Edition)2009，83，4： | 7 |
| 12 | Petrogenesis of the concealed Daqiling intrusion in Guangxi and its tectonic significance: Constraints from geochemistry, zircon U-Pb dating and Nd-Hf isotopic compositions显示文摘The samples from the hidden Daqiling muscovite monzonite granite, which has recently been recognized within the Limu Sn-polymetallic ore field, have been analyzed for zircon U-Pb ages and whole rock geochemical and Nd-Hf isotopic compositions to discuss its genesis, source, and tectonic setting. LA-ICP-MS zircon U-Pb dating indicates that the granite crystallized in the late Indosinian(224.8±1.6 Ma). The granite is enriched in SiO2 and K2 O and low in CaO and Na2 O. It is strongly peraluminous with the A/CNK values of 1.09–1.20 and 1.4 vol%–2.7 vol% normal corundum. Chondrite-normalized REE patterns show slightly right-dipping shape with strongly negative Eu anomalies(δEu =0.08–0.17). All samples show enrichment of LILEs(Cs, Rb and K) and HFSEs(U, Pb, Ce and Hf), but have relatively low contents of Ba, Sr and Ti. The zircon saturation temperatures(Tzr) are from 711 to 740℃, which are slightly lower than the average value of typical S-type granite(764℃). The granite has negative εNd(t) and εHf(t) values, which change from -9.1 to -10.1 with the peak values of -9.2 to -9.0 and from -3.7 to -12.6 with the peak values of -6 to -5, respectively. The C DMT(Nd) and C DMT(Hf) values are 1.74–1.82 Ga with the peak values of 1.73–1.75 Ga and 1.49–2.04 Ga with the peak values of 1.5–1.6 Ga, respectively. These characteristics reveal that the source region of the granite is dominantly late Paleoproterozoic to early Mesoproterozoic crustal materials. Seven inherited magmatic zircons are dated at the age of 248.6±4.3 Ma, which suggests the existence of the early Indosinian granite in Limu area. These zircons have the εHf(t) values of -6.7– -2.3, similar to those of the Daqiling granite, implying the involvement of the early Indosinian granite during the formation of the Daqiling granite. Inherited zircon of 945±11 Ma has the εHf(t) and TDM(Hf) values of 8.7 and 1.14 Ga, respectively, compatible with those of the Neoproterozoic arc magmatic rocks in the eastern Jiangnan orogenic belt. Therefore we inferred that Neoproterozoic arc magma might have been involved in the formation of the Daqiling granite, and that the Neoproterozoic arc magma belt and continent-arc collision belt between the Yangtze and Cathaysia Blocks might have extended westsouthward to Limu region. It is proposed that the underplating of mantle materials triggered by crustal extension and thinning resulted in partial melting of crustal materials to form the Daqiling granite in the late Indosinian under post-collisional tectonic setting. | ZHANG HuaiFeng LU JianJun WANG RuCheng MA DongSheng ZHU JinChu ZHANG RongQing | 2014 | Science China Earth Sciences2014，57，8： | 6 |
| 13 | Electrical transport properties of Fe Se single crystal under high magnetic field显示文摘Understanding the normal electronic state is crucial for unveiling the mechanism of unconventional superconductivity(SC). In this paper, by applying a magnetic field of up to 37T on FeSe single crystals, we could reveal the normal-state transport properties after SC was completely suppressed. The normal-state resistivity exhibited a Fermi liquid behavior at low temperatures. Large orbital magnetoresistance(MR) was observed in the nematic state with H//c, whereas MR was negligible with H//ab. The magnitude of the orbital MR showed an unusual reduction, and Kohler’s rule was severely violated below 10-25 K;these were attributable to spin fluctuations. The results indicated that spin fluctuations played a paramount role in the normalstate transport properties of FeSe albeit the Fermi liquid nature was at low temperature. | HongHui Wang ZhaoHui Cheng MengZhu Shi DongHui Ma WeiZhuang Zhuo ChuanYing Xi Tao Wu JianJun Ying XianHui Chen | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 6 |
| 14 | Complete three-dimensional coseismic displacements due to the 2021 Maduo earthquake in Qinghai Province,China from Sentinel-1 and ALOS-2 SAR images显示文摘On 22 nd May 2021(local time),an earthquake of M_(s)7.4 struck Maduo county in Qinghai Province,China.This was the largest earthquake in China since the 2008 Wenchuan earthquake.In this study,ascending/descending Sentinel-1 and advanced land observation satellite-2(ALOS-2)synthetic aperture radar(SAR)images were used to derive the three-dimensional(3-D)coseismic displacements of this earthquake.We used the differential interferometric SAR(In SAR,DIn SAR),pixel offset-tracking(POT),multiple aperture In SAR(MAI),and burst overlap interferometry(BOI)methods to derive the displacement observations along the line-of-sight(LOS)and azimuth directions.To accurately mitigate the effect of ionospheric delay on the ALOS-2 DIn SAR observations,a polynomial fitting method was proposed to optimize range-spectrum-split-derived ionospheric phases.In addition,the 3-D displacement field was obtained by a strain model and variance component estimation(SM-VCE)method based on the high-quality SAR displacement observations.Results indicated that a left-lateral fault slip with the largest horizontal displacement of up to 2.4 m dominated this earthquake,and the small-magnitude vertical displacement with an alternating uplift/subsidence pattern along the fault trace was more concentrated in the near-fault regions.Comparison with the global navigation satellite system data indicated that the SM-VCE method can significantly improve the accuracy of the displacements compared to the classical weighted least squares method,and the incorporation of the BOI displacements can substantially benefit the accuracy of north-south displacement.In addition to the displacements,three coseismic strain invariants calculated based on the strain model parameters were also investigated.It was found that the eastern and western parts of the faults suffered more significant strains compared with the epicenter region. | Jihong LIU Jun HU Zhiwei LI Zhangfeng MA Lixin WU Weiping JIANG Guangcai FENG Jianjun ZHU | 2022 | Science China Earth Sciences2022，65，4： | 6 |

| 18 | Effect of Al on Microstructures and Mechanical Properties of the Ultrahigh Carbon Steels显示文摘In this research, we tried to find a simple processing method to break up the network carbides in ultrahigh carbon steels (UHCS). Our results revealed that Al addition was favorable to the decrease in the proeutectoid carbides, the pearlite-colony size and the pearlitic interlamellar spacing of the forged microstructures, and that a fully-pearlitic structure was obtained in the UHCS containing 1.6 wt pct Al. The quenching-and-tempering process resulted in fine microstructure in those steels. On the other hand, the strength of the UHCSs increased with the increase of the Al content, and the highest strength was obtained at the UHCS with 1.6 wt pct Al. The UHCSs with Al contents higher than 1.3 wt pct showed a high tensile strength of more than σb=1000 MPa and good ductility of higher than δ5=10% at ambient temperature. | Huifen PENG, Baoqi WANG, Jianjun ZHANG, Xiaoyan SONG, Xiaoli MA and Nanju GUSchool of Materials Science & Engineering, Hebei University of Techonology, Tianjin 300130, China | 2004 | Journal of Materials Science & Technology2004，20，5： | 5 |
| 19 | Computational fluid dynamics simulation of friction stir welding:A comparative study on different frictional boundary conditions显示文摘Numerical simulation based on computational fluid dynamics(CFD) is a useful approach for quantitatively investigating the underlying thermal-mechanical conditions during FSW, such as temperature field and material deformation field. One of the critical issues in CFD simulation of FSW is the use of the frictional boundary condition, which represents the friction between the welding tool and the workpiece in the numerical models. In this study, three-dimensional numerical simulation is conducted to analyze the heat transfer and plastic deformation behaviors during the FSW of AA2024. For comparison purposes,both the boundary velocity(BV) models and the boundary shear stress(BSS) models are employed in order to assess their performances in predicting the temperature and material deformation in FSW. It is interesting to note that different boundary conditions yield similar predictions on temperature, but quite different predictions on material deformation. The numerical predictions are compared with the experimental results. The predicted deformation zone geometry by the BSS model is consistent with the experimental results while there is large difference between the predictions by the BV models and the experimental measurements. The fact that the BSS model yields more reasonable predictions on the deformation zone geometry is attributed to its capacity to automatically adjust the contact state at the tool/workpiece interface. Based on the favorable predictions on both the temperature field and the material deformation field, the BSS model is suggested to have a better performance in numerical simulation of FSW than the BV model. | Gaoqiang Chen Qingxian Ma Shuai Zhang Jianjun Wu Gong Zhang Qingyu Shi | 2018 | Journal of Materials Science & Technology2018，34，1： | 5 |
| 20 | Synthesis of polycrystalline γ-AlON powders by novel wet chemical processing显示文摘The synthesis of polycrystalline aluminum oxynitride (AlON) powders was investigated by the carbothermal reduction and nitridation (CRN) of amorphous precursor obtained by wet chemical processing. Co-precipitation processing was employed to achieve amorphous precursor from Al(NO3)3 solution dispersed by nanosized carbon particles, which was composed of Al(OH)3 and C particles homogeneously. The effects of the content of carbon black, pH value, and calcination temperature on formation of AlON phase were investigated by means of XRD, SEM and TEM, respectively. It was found that single phase AlON powder could be synthesized when the resultant precursors were calcined at 1750°C for 2 hours under flowing N2 . Under optimal additional content of C (5.6wt%), the resultant AlON powders exhibited the primary particle size of about 1-3 μm with a specific surface area of 3.2m2/g, which were superior to that of carbothermal reduction of immediate mixture of γ-Al2O3/C powders. | LEI JingXuan MA FeiZhong SHI Ying XIE JianJun HU Wei SHI ZhiWei | 2012 | Science China(Technological Sciences)2012，55，12： | 4 |
