| 1 | Stress Corrosion Cracking of X80 Steel in the Presence of Sulfate-reducing Bacteria显示文摘The systematic laboratory studies on the roles of sulfate-reducing bacteria(SRB) in the stress corrosion cracking(SCC) susceptibility of X80 steel subjected to cathodic potential have been conducted in a nearneutral pH soil solution by slow strain rate tests.The cathodic potential and SRB increase individually the SCC susceptibility of the steel in the soil solution.The positive role of the SRB activities in SCC susceptibility depends on the prolongation of pre-incubation time,and the SCC susceptibility of the steel increases under more negative potentials.What's more,the applied potentials and the presence of SRB work together in promoting the SCC susceptibility of the steel.But,the combined action becomes limited with decreasing cathodic potentials.The relationships between the plasticity loss and the permeable hydrogen concentration were established for the steel in the soil solution,regardless of under open circuit potential or cathodic potentials,in both the sterile and SRB inoculated conditions.The relationships are practically significant for the selection of safe cathodic protection(CP) potentials in the presence of SRB in soil environment. | Tangqing Wu Maocheng Yan Dechun Zeng Jin Xu Cheng Sun Changkun Yu Wei Ke | 2015 | Journal of Materials Science & Technology2015，31，4： | 11 |

| 9 | Experimental and numerical study on the dynamic shear banding mechanism of HfNbZrTi high entropy alloy显示文摘High-entropy alloys(HEAs) have attracted considerable attention in recent years because of their unique mechanical properties.In this work, the mechanism of dynamic shear banding(also called adiabatic shear bands, ASBs) in a BCC HEA HfNbZrTi was investigated combining dynamic experiments and numerical simulations. The temperature evolution during dynamic shear banding, which has been believed to play a dominant role during ASB formation in the literature, was measured using high-speed infrared thermal detectors synchronized with a split Hopkinson pressure bar system. The dynamic mechanical behavior of the BCC HEA was described using the Johnson-Cook model accompanied by damage accumulation. The process of ASB formation,considering potential contributions from thermal softening and damage softening, was numerically investigated by controlling the activation of each softening mechanism separately. Based on the results of experimental observation and numerical analysis,dynamic shear banding in this BCC HEA is proposed to be dominated by damage softening, and thermal softening only plays a secondary role, which differs from the thermal-softening-dominated ASB formation in typical FCC HEAs such as the Cantor alloy. | SONG Wei-Li MA Quan ZENG QingLei ZHU ShengXin SUI MingBin CAO TangQing QI Wei CHEN YinQiang YU XiaoQi XUE YunFei CHEN Hao-Sen | 2022 | Science China(Technological Sciences)2022，65，8： | 1 |

| 16 | Dynamic recrystallization-induced temperature insensitivity of yield stress in single-crystal Al1.2CrFeCoNi micropillars显示文摘High-entropy alloys, a new class of metallic materials, exhibit excellent mechanical properties at high temperatures. In spite of the worldwide interest, the underlying mechanisms for temperature dependence of mechanical properties of these alloys remain poorly understood. Here, we systemically investigate the mechanical behaviors and properties of Al_(1.2)CrFeCoNi(comprising a body-centered cubic phase) and Al_(0.3)CrFeCoNi(comprising a face-centered cubic phase) single-crystal micropillars with three orientations([100], [110], and [111]) at temperatures varying from 300 to 675 K by using in situ compression of micropillars inside a scanning electron microscope. The results show that the yield stresses of Al_(1.2)CrFeCoNi micropillars are insensitive to temperature changes, and their flow stresses and work hardening rates increase slightly with increasing temperature from 300 to550 K, which differs from the typical temperature dependence of yield/flow stresses in metals and alloys. In contrast,Al_(0.3)CrFeCoNi micropillars exhibit typical thermal softening. Furthermore, it is found that the Al_(1.2)CrFeCoNi micropillars exhibit a transition from homogenous deformation to localized deformation at a critical temperature, while the Al_(0.3)CrFeCoNi micropillars always maintain a well-distributed and fine slip deformation. Detailed transmission electron microscopy analyses reveal that dynamic recrystallization(involving dislocation tangles, and formation of dislocation cell structures and sub-grains)plays a key role in the observed temperature insensitivity of the yield stress and increasing flow stress(and work hardening rate)with increasing temperature in the Al_(1.2)CrFeCoNi micropillars, and that thermally activated dislocation slip leads to thermal softening of the Al_(0.3)CrFeCoNi micropillars. The differences in deformation modes and temperature dependence of the mechanical properties between Al_(1.2)CrFeCoNi and Al_(0.3)CrFeCoNi essentially originate from the differences in dislocation activities and slip systems since the two alloys adopt different phases. Our findings provide key insights in the temperature dependence of mechanical properties and deformation behaviors of high-entropy alloys with body-centered cubic and face-centered cubic phases. | HUANG RuiRui ZHANG Qian ZHANG Xuan LI JianGuo CAO TangQing YAO JiaHao XUE YunFei GAO HuaJian LI XiaoYan | 2021 | Science China(Technological Sciences)2021，64，1： | 1 |
| 17 | Silica photonic crystals with quasi-full band gap in the visible region prepared in ethanol显示文摘Monodisperse silica spheres of 252 nm with a standard deviation of 5.7% are prepared by Stber method. By comparison of both of media, ethanol instead of water is used to assemble opal, and the artificial opal has been prepared by the sedimentation in ethanol of silica spheres. The structure of the opal prepared has been examined and discussed. The results show that the artificial opal has a structure similar to the face-centered cubic (fcc) type packed system with silica spheres. Transmission measurements of the artificial opal have been conducted, which shows that the artificial opal is quasi-full band gap silica photonic crystals in the visible region. | ZHANGHui WANGXidong ZHAOXiaofeng LlWenchao TANGQing | 2003 | Progress in Natural Science:Materials International2003，13，9： | 1 |
| 18 | Solid-State Hydrogen Storage Properties of Ti-V-Nb-Cr High-Entropy Alloys and the Associated Effects of Transitional Metals(M=Mn,Fe,Ni)显示文摘Recently,high-entropy alloys(HEAs)designed by the concepts of unique entropy-stabilized mechanisms,started to attract widespread interests for their hydrogen storage properties.HEAs with body-centered cubic(BCC)structures present a high potential for hydrogen storage due to the high hydrogen-to-metal ratio(up to H/M=2)and vastness of compositions.Although many studies reported rapid absorption kinetics,the investigation of hydrogen desorption is missing,especially in BCC HEAs.We have investigated the crystal structure,microstructure and hydrogen storage performance of a series of HEAs in the Ti-V-Nb-Cr system.Three types of TiVCrNb HEAs(Ti_(4)V_(3)NbCr_(2),Ti_(3)V_(3)Nb2Cr_(2),Ti_(2)V_(3)Nb_(3)Cr_(2))with close atomic radii and different valence electron concentrations(VECs)were designed with single BCC phase by CALPHAD method.The three alloys with fast hydrogen absorption kinetics reach the H/M ratio up to 2.Particularly,Ti_(4)V_(3)NbCr_(2)alloy shows the hydrogen storage capacity of 3.7 wt%,higher than other HEAs ever reported.The dehydrogenation activation energy of HEAs’hydride has been proved to decrease with decreasing VEC,which may be due to the weakening of alloy atom and H atom.Moreover,Ti_(4)V_(3)NbCr_(2)M(M=Mn,Fe,Ni)alloys were also synthesized to destabilize hydrides.The addition of Mn,Fe and Ni lead to precipitation of Laves phase,however,the kinetics did not improve further because of their own excellent hydrogen absorption.With increasing the content of Laves phase,there appear more pathways for hydrogen desorption so that the hydrides are more easily dissociated,which may provide new insights into how to achieve hydrogen desorption in BCC HEAs at room temperature. | Bo Cheng Yunkai Li Xiaoxi Li Huibin Ke Liang Wang Tangqing Cao Di Wan Benpeng Wang Yunfei Xue | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，7： | 0 |
| 19 | Climate warming suppresses abundant soil fungal taxa and reduces soil carbon efflux in a semi-arid grassland显示文摘Soil microorganisms critically affect the ecosystem carbon(C)balance and C-climate feedback by directly controlling organic C decomposition and indirectly regulating nutrient availability for plant C fixation.However,the effects of climate change drivers such as warming,precipitation change on soil microbial communities,and C dynamics remain poorly understood.Using a long-term field warming and precipitation manipulation in a semi-arid grassland on the Loess Plateau and a complementary incubation experiment,here we show that warming and rainfall reduction differentially affect the abundance and composition of bacteria and fungi,and soil C efflux.Warming significantly reduced the abundance of fungi but not bacteria,increasing the relative dominance of bacteria in the soil microbial community.In particular,warming shifted the community composition of abundant fungi in favor of oligotrophic Capnodiales and Hypocreales over potential saprotroph Archaeorhizomycetales.Also,precipitation reduction increased soil total microbial biomass but did not significantly affect the abundance or diversity of bacteria.Furthermore,the community composition of abundant,but not rare,soil fungi was significantly correlated with soil CO_(2) efflux.Our findings suggest that alterations in the fungal community composition,in response to changes in soil C and moisture,dominate the microbial responses to climate change and thus control soil C dynamics in semi-arid grasslands. | Yunpeng Qiu Kangcheng Zhang Yunfeng Zhao Yexin Zhao Bianbian Wang Yi Wang Tangqing He Xinyu Xu Tongshuo Bai Yi Zhang Shuijin Hu | 2023 | mLife2023，2，4： | 0 |
