| 1 | 搅拌铸造SiC颗粒增强铝基复合材料的组织与磨损性能(英文)显示文摘研究SiC颗粒增强体(粒径为1、5、20和50μm;体积分数为5%、10%和15%)对Al基复合材料组织和磨损性能的影响。采用搅拌铸造工艺制备复合材料,采用盘销式磨损试验测试Al基体和复合材料在不同载荷下的干滑动摩擦磨损性能。考察冷轧压下量对复合材料干滑动磨损性能的影响。对磨损表面和磨屑进行硬度测试和SEM观察。结果表明,搅拌铸造工艺参数包括浇注温度、搅拌速度、搅拌时间、增强体颗粒预热温度等影响所制备材料的质量。为使材料具有较好的性能,应将复合材料中的孔隙度降至最小,尽量避免增强体颗粒与基体之间的化学反应。 | Ali MAZAHERY Mohsen Ostad SHABANI | 2013 | Transactions of Nonferrous Metals Society of China2013，23，7： | 15 |
| 2 | Computational fluid dynamics(CFD) simulation of effect of baffles on separation in mixer settler显示文摘The main ideas in the development of the solvent extraction mixer settler focused on achieving clean phase separation,minimizing the loss of the reagents and decreasing the surface area of the settlers.The role of baffles in a mechanically agitated vessel is to ensure even distribution,reduce settler turbulence,promote the stability of power drawn by the impeller and to prevent swirling and vortexing of liquid,thus,greatly improving the mixing of liquid.The insertion of the appropriate number of baffles clearly improves the extent of liquid mixing.However,excessive baffling would interrupt liquid mixing and lengthen the mixing time.Computational fluid dynamics(CFD) provides a tool for determining detailed information on fluid flow(hydrodynamics) which is necessary for modeling subprocesses in mixer settler.A total of 54 final CFD runs were carried out representing different combinations of variables like number of baffles,density and impeller speed.CFD data shows that amount of separation increases with increasing baffles number and decreasing impeller speed. | Mohsen Ostad Shabani Ali Mazahery Mehdi Alizadeh Ali Asghar Tofigh Mohammad Reza Rahimipour Mansour Razavi Alireza Kolahi | 2012 | International Journal of Mining Science and Technology2012，22，5： | 12 |
| 3 | SiC纳米颗粒增强A356铸造合金的表征(英文)显示文摘通过搅拌铸造制备SiC纳米颗粒增强A356铝合金复合材料,并研究其显微组织和力学性能。密度测量发现试样的孔隙度较低,且孔隙度随SiC颗粒体积分数的增加而增加。通过光学显微镜和透射电镜观察材料的显微组织,发现弥散的颗粒分布均匀。材料的拉伸强度和弹性模量随加入纳米SiC颗粒的增加而提高,而延展性有所降低。当SiC纳米颗粒的加入量为3.5%时,复合材料的屈服强度和极限抗拉强度达到最高。断口分析表明,拉伸断裂试样为相对韧性断裂。 | Ali MAZAHERY Mohsen Ostad SHABANI | 2012 | Transactions of Nonferrous Metals Society of China2012，22，2： | 11 |
| 4 | Effects of different periods of renal ischemia on liver as a remote organ显示文摘AIM:To assess the hepatic changes after induction of different periods of renal ischemia. METHODS:Rats were subjected to either sham operation or ischemia (30,45 and 60 min) followed by 60 min reperfusion. Liver and renal functional indices were measured. Hepatic glutathione (GSH) and ferric reducing antioxidant power levels and the concentration of interleukin (IL)-10 and tumor necrosis factor (TNF-α) were evaluated. Portions of liver and kidney tissues were fixed for histological evaluation. RESULTS:Forty-five minutes renal ischemia followed by 60 min reperfusion caused significant changes in liver structure and a significant reduction in renalfunction. These rats showed a significant decrease in liver GSH,as well as a significant increase in TNF-α and IL-10 concentrations. These results demonstrated that renal ischemia caused changes in liver histology,function,oxidative stress and inflammatory status,which led to a reduction in hepatic antioxidant capacity. With 30 min ischemia,the magnitude of these changes was less than those with 45 or 60 min ischemia.CONCLUSION:A minimum of 45 min ischemia is needed to study the effects of renal injury on the liver as a remote organ. | Mehri Kadkhodaee Fereshteh Golab Maryam Zahmatkesh Rana Ghaznavi Mehdi Hedayati Hossein Ali Arab Seyed Naser Ostad Manoocher Soleimani | 2009 | World Journal of Gastroenterology2009，15，9： | 5 |

| 6 | Application of the Extrusion to Increase the Binding between the Ceramic Particles and the Metal Matrix:Enhancement of Mechanical and Tribological Properties显示文摘Aluminum alloyed with magnesium and silicon has been used as the matrix material owing to its excellent mechanical properties coupled with good formability and its wide applications in industrial sector.An extrusion process was developed to consolidate Al 6061—SiCp composites from mixed powders.The results show that the composites were fully densified,with no sign of pores or oxide layers observable in the optical microscope.The SiC particles were distributed uniformly in the matrix.As compared with 6061 alloys,the composites demonstrated a smaller elongation,but exhibited a higher Young's modulus and a larger work hardening capacity.These composites possessed much higher elongation at the same strength level.The present study also addressed the dry wear behavior of the composites at different sliding speeds and applied loads.Values of the friction coefficient of the matrix alloy and composite materials were in expected range for light metals in dry sliding conditions.All of these improvements were attributed to the merits,including full densification of the bulk,uniform dispersion of the SiC particles in the matrix,and strong binding between the SiC particles and the matrix resulting from the extrusion. | Ali Mazahery Mohsen Ostad Shabani | 2013 | Journal of Materials Science & Technology2013，29，5： | 3 |
