| 1 | 新型强塑性变形—静液循环挤压压缩加工AZ91镁合金及其表征显示文摘通过静液循环挤压压缩(HCEC)强塑性变形法加工具有较大高径比的密排六方金属棒,并研究其性能。对AZ91镁合金进行两个连续循环加工,研究其显微组织演化、力学性能和腐蚀行为。结果表明,HCEC加工可成功制备超细晶镁合金长棒材,且可同时提高其强度和韧性。经二次循环加工后,样品的抗拉强度和伸长率分别为铸态样品的2.46倍和3.8倍,显微硬度分布更加均匀,其平均值增加了116%。对于加工后的样品,从极化曲线得到的电位较高,电流较低,从Nyquist曲线得到的电容弧直径更大。有限元分析表明,与传统的循环挤压压缩相比,HCEC载荷与长度无关。HCEC是一种特殊的强塑性变形方法,可以制备兼具良好力学性能和耐腐蚀性能的超细晶镁合金长棒材。 | Armin SIAHSARANI Ghader FARAJI | 2021 | Transactions of Nonferrous Metals Society of China2021，31，5： | 11 |
| 2 | Microstructure and mechanical properties of Al/Cu/Mg laminated composite sheets produced by the ARB proces显示文摘In the present study, an Al/Cu/Mg multi-layered composite was produced by accumulative roll bonding(ARB) through seven passes, and its microstructure and mechanical properties were evaluated. The microstructure investigations show that plastic instability occurred in both the copper and magnesium reinforcements in the primary sandwich. In addition, a composite with a perfectly uniform distribution of copper and magnesium reinforcing layers was produced during the last pass. By increasing the number of ARB cycles, the microhardness of the layers including aluminum, copper, and magnesium was significantly increased. The ultimate tensile strength of the sandwich was enhanced continually and reached a maximum value of 355.5 MPa. This strength value was about 3.2, 2, and 2.1 times higher than the initial strength values for the aluminum, copper, and magnesium sheets, respectively. Investigation of tensile fracture surfaces during the ARB process indicated that the fracture mechanism changed to shear ductile at the seventh pass. | Davood Rahmatabadi Moslem Tayyebi Ramin Hashemi Ghader Faraji | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，5： | 10 |
| 3 | Extraction and determination of trace amounts of chlorpromazine in biological fluids using magnetic solid phase extraction followed by HPLC显示文摘A simple,rapid and sensitive method termed as magnetic solid phase extraction(MSPE)combined with high-performance liquid chromatography-ultraviolet detector(HPLC-UV) has been proposed for the delcmiination of trace amounts of chlorproma/ine(CPZ) in water,urine and plasma samples.The separation and determination was performed on a CI8 column under the optimal chromatographic conditions.Several factors influencing the extraction efficiency of CPZ.such as pH.surfactant and adsorbent amounts,ionic strength,extraction time,sample volume and desorption conditions,were studied and optimized.Under the optimal MSPE conditions,the extraction percentage of CPZ was 74%.27%and 16%in water,urine and plasma samples,respectively.The limits of detection(LODs) of the proposed approach were 0.1.5.0 and 10ng/mL in water,urine and plasma samples,respectively.The relative standard deviations(RSDs) based on five replicate determinations at K)ng/mL level of CPZ was 1.2%.Good linear behaviors over the investigated concentration ranges(0.25-300ng/mL) with good coefficient of determination,R^2>0.9998.were obtained.Good spike recoveries with relative errors less than 9.0%were obtained when applying the proposed method to water,urine and plasma samples. | Yadollah Yamini Mohammad Faraji | 2014 | Journal of Pharmaceutical Analysis2014，4，4： | 9 |
| 4 | High-fidelity replication of thermoplastic microneedles with open microfluidic channels显示文摘Development of microneedles for unskilled and painless collection of blood or drug delivery addresses the quality of healthcare through early intervention at point-of-care.Microneedles with submicron to millimeter features have been fabricated from materials such as metals,silicon,and polymers by subtractive machining or etching.However,to date,large-scale manufacture of hollow microneedles has been limited by the cost and complexity of microfabrication techniques.This paper reports a novel manufacturing method that may overcome the complexity of hollow microneedle fabrication.Prototype microneedles with open microfluidic channels are fabricated by laser stereolithography.Thermoplastic replicas are manufactured from these templates by soft-embossing with high fidelity at submicron resolution.The manufacturing advantages are(a)direct printing from computeraided design(CAD)drawing without the constraints imposed by subtractive machining or etching processes,(b)high-fidelity replication of prototype geometries with multiple reuses of elastomeric molds,(c)shorter manufacturing time compared to three-dimensional stereolithography,and(d)integration of microneedles with open-channel microfluidics.Future work will address development of open-channel microfluidics for drug delivery,fluid sampling and analysis. | Zahra Faraji Rad Robert E.Nordon Carl J.Anthony Lynne Bilston Philip D.Prewett Ji-Youn Arns Christoph H.Arns Liangchi Zhang Graham J.Davies | 2017 | Microsystems & Nanoengineering2017，3，1： | 9 |
| 5 | 新型SPD工艺对AM60镁合金性能不均匀性的影响显示文摘利用新型大塑性变形(SPD)技术提高镁合金的冶金性能。在此过程中,先进行循环挤压−压缩−角挤压(CECAP)过程,再在出口处进行挤压,起到附加背压的作用。因此,与等径角挤压(ECAP)相比,期望获得更加均匀和优异的力学性能。为了评价这种新方法的有效性和能力,对AM60镁合金进行加工。有限元分析表明,新方法的应变值和均匀应变分布均显著提高。此外,与传统的ECAP相比,新方法的压应力增加约110%。实验结果表明,经新工艺处理后,试样的硬度和强度均有显著提高,这是由于其晶粒细化,显微组织更加均匀,并且细化的β相沿晶界均匀分布。因此,该新工艺在未来镁合金生产中具有广阔的应用前景。 | Siroos AHMADI Vali ALIMIRZALOO Ghader FARAJI Ali DONIAVI | 2021 | Transactions of Nonferrous Metals Society of China2021，31，3： | 8 |
| 6 | Recrystallization and mechanical properties of WE43 magnesium alloy processed via cyclic expansion extrusion显示文摘In this study, cyclic expansion extrusion(CEE), as a relatively new severe plastic deformation(SPD) process, is applied to a rare earth(RE) containing Mg alloy WE43. The effects of the processing temperature and the number of passes are also investigated. The results showed that dynamic recrystallization(DRX) occurred after CEE processing at 400°C, and a bimodal structure with ultrafine DRXed grains surrounded the unrecrystallized grains. However, the DRX at 330°C was retarded because of the existence of RE elements. The tensile tests showed that a simultaneous increase in the strength and the ductility of WE43 is obtained after CEE processing at 400°C via two passes. Furthermore, the highest ultimate tensile strength of 440 MPa was achieved after the second pass of CEE at 330°C, and the highest ductility of 21% was attained after the second pass of CEE at 400°C. The microhardness measurements showed that the hardness increased from HV 80 to HV 114 and HV 98 after two passes of CEE processing at 330 and 400°C, respectively. In conclusion, increasing the processing passes could increase the mechanical properties and the volume fraction of the recrystallized grains. Moreover, increasing the temperature reduced the strength and the microhardness even if the elongation increased. | Soheil Amani Ghader Faraji | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，6： | 7 |
| 7 | Role of international criteria in the diagnosis of autoimmune hepatitis显示文摘AIM: To study the clinical and laboratory characteristics of autoimmune hepatitis (AIH), and compare them with International Autoimmune Hepatitis Group (IAHG) criteria. METHODS: Sixty consecutive patients with AIH attended the University Clinic at Tabriz University of Medical Sciences, Iran for a 12mo period and were assessed in a case series study. Serological and biochemical evaluations were carried out in all patients. Autoantibodies, such as antinuclear antibody (ANA), anti-smooth muscle antibody (ASMA), anti-liver-kidney microsomal antibody (ALKM-1) type 1, and perinuclear anti-neutrophil cytoplasmic antibodies (P-ANCA) were evaluated in these patients. A liver biopsy was performed after diagnosis of the disease. Patients were evaluated in terms of their signs and symptoms, and laboratory results and the degree to which they corresponded with the diagnostic criteria of IAHG. In this study, both a comprehensive diagnostic scoring system and a simplified diagnostic scoring system were employed for AIH.RESULTS: Sixty patients, 2-0 male, 40 female, mean age 39.45 ± 17.50 years, participated in the study. Treatment began immediately after enrolment into the study. The percent distribution of the study population into definite and probable did not change after the treatment. The most common symptoms in descending order were fatigue (100%), icter (66.7%), abdominal discomfort (33.3%), abdominal distension (2-8.3%), dark urine (2-3.3%), edema (2-3.3%), hematemesis (2-0.0%), pruritus (2-0.0%), melena (11.7%) and pale stool (10.0%). At the physical examination, splenomegaly, ascites, hepatomegaly, epigastric tenderness and an abdominal mass were found in 50.0%, 16.7%, 13.3%, 5.0% and 3.3% of patients, respectively. Hypergammaglobulinemia was detected in 95.0% of cases. ALKM-1, P-ANCA, ANA and ASMA were positive in 71.4%, 66.7%, 42-.4% and 19.4% of cases, respectively. Portal hypertensive gastropathy (45.0%), esophageal varices (41.7%) and cirrhosis (40.0%) were the most prevalent complications of AIH, and there was no evidence of primary sclerosing cholangitis, ulcerative colitis and overlap syndrome in these patients. According to IAHG criteria, 80.0% of cases had a definite diagnosis, 15.0% had a probable diagnosis and 5.0% had no AIH. The percent distribution of the study population into definite, probable and no AIH did not change after using the simplified diagnostic scoring system for AIH. CONCLUSION: This research showed that the majority of cases in our study were appropriately diagnosed according to the IAHG criteria and simplified scoring system. Thus, these criteria are very useful. | Mohammad Reza Abdollahi Mohammad Hossein Somi Esmaeil Faraji | 2013 | World Journal of Gastroenterology2013，19，23： | 5 |

| 9 | Processing of AM60 magnesium alloy by hydrostatic cyclic expansion extrusion at elevated temperature as a new severe plastic deformation method显示文摘Hydrostatic cyclic expansion extrusion(HCEE) process at elevated temperatures is proposed as a method for processing less deformable materials such as magnesium and for producing long ultrafine-grained rods. In the HCEE process at elevated temperatures, high-pressure molten linear low-density polyethylene(LLDPE) was used as a fluid to eliminate frictional forces. To study the capability of the process,AM60 magnesium rods were processed and the properties were investigated. The mechanical properties were found to improve significantly after the HCEE process. The yield and ultimate strengths increased from initial values of 138 and 221 MPa to 212 and 317 MPa, respectively.Moreover, the elongation was enhanced due to the refined grains and the existence of high hydrostatic pressure. Furthermore, the microhardness was increased from HV 55.0 to HV 72.5. The microstructural analysis revealed that ultrafine-grained structure could be produced by the HCEE process. Moreover, the size of the particles decreased, and these particles thoroughly scattered between the grains. Finite element analysis showed that the HCEE was independent of the length of the sample, which makes the process suitable for industrial applications. | Farshad Samadpour Ghader Faraji Armin Siahsarani | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，5： | 4 |
| 10 | Investigation of effective dimensionless numbers on initiation of instability in combustion of moisty organic dust显示文摘In this work,the effect of various effective dimensionless numbers and moisture contents on initiation of instability in combustion of moisty organic dust is calculated.To have reliable model,effect of thermal radiation is taken into account.One- dimensional flame structure is divided into three zones: preheat zone,reaction zone and post-flame zone.To investigate pulsating characteristics of flame,governing equations are rewritten in dimensionless space-time(ξ,η,τ) coordinates.By solving these newly achieved governing equations and combining them,which is completely discussed in body of article,a new expression is obtained.By solving this equation,it is possible to predict initiation of instability in organic dust flame.According to the obtained results by increasing Lewis number,threshold of instability happens sooner.On the other hand,pulsating is postponed by increasing Damk?hler number,pyrolysis temperature or moisture content.Also,by considering thermal radiation effect,burning velocity predicted by our model is closer to experimental results. | Mehdi Bidabadi Farzad Faraji Dizaji Hossein Beidaghy Dizaji Moslem Safari Ghahsareh | 2014 | Journal of Central South University2014，21，1： | 4 |

| 13 | An analytical model for pyrolysis of a single biomass particle显示文摘Decreasing in emissions of greenhouse gases to confront the global warming needs to replace fossil fuels as the main doer of the world climate changes by renewable and clean fuels produced from biomass like wood waste which is neutral on the amount of CO2. An analytical and engineering model for pyrolysis process of a single biomass particle has been presented. Using a two-stage semi global kinetic model which includes both primary and secondary reactions, the effects of parameters like shape and size of particle as well as porosity on the particle temperature profile and product yields have been investigated. Comparison of the obtained results with experimental data shows that our results are in a reasonable agreement with previous researchers' works. Finally, a sensitivity analysis is done to determine the importance of each parameter on pyrolysis of a single biomass particle which is affected by many constant parameters. | Mehdi Bidabadi Mohammad Rastegar Moghaddam Seyed Alireza Mostafavi Farzad Faraji Dizaji Hossein Beidaghy Dizaji | 2015 | Journal of Central South University2015，22，1： | 3 |
| 14 | Micro-organic dust combustion considering particles thermal resistance显示文摘Organic dust flames deal with a field of science in which many complicated phenomena like pyrolysis or devolatization of solid particles and combustion of volatile particles take place. One-dimensional flame propagation in cloud of fuel mixture is analyzed in which flame structure is divided into three zones. The first zone is preheat zone in which rate of the chemical reaction is small and transfer phenomena play significant role in temperature and mass distributions. In this model, it is assumed that particles pyrolyze first to yield a gaseous fuel mixture. The second zone is reaction zone where convection and vaporization rates of the particles are small. The third zone is convection zone where diffusive terms are negligible in comparison of other terms. Non-zero Biot number is used in order to study effect of particles thermal resistance on flame characteristics. Also, effect of particle size on combustion of micro organic dust is investigated. According to obtained results, it is understood that both flame temperature and burning velocity decrease with rise in the Biot number and particle size. | Mohammadamin Soltaninejad Farzad Faraji Dizaji Hossein Beidaghy Dizaji Mehdi Bidabadi | 2015 | Journal of Central South University2015，22，7： | 2 |
