Research Institute for Nonferrous Metals, Beijing 100088, China摘 要:The microstructure of the as-cast 7A55 aluminum alloy and its evolution during homogenization..., and intermetallic compounds MgZn2, Al2CuMg, Al7Cu2Fe, and Al23CuFe4. After homogenization at 470°C for 48 h, Al/AlZnMgCu eutectic phases are dissolved into the matrix, and a small amount of high melting-point......
Dynamic softening and microstructural evolution during hot deformation of Al-Cu-Mg-Zr alloys with different homogenization cooling ratesGuo-Wei Bo1,Guan Wang2,Fu-Lin Jiang1,Can Liu1,Rong Chen1,Hui... obtained different homogenization cooling rates by changing the heattreated sample size,was compressed to various strains at the deformation temperature of 300℃ and strain rate of0.01 s-1.The results......
evolutions of two Al-Zn-Mg alloys, one of which was alloyed with Sc and Zr, and the kinetics of Al3(Sc1-xZrx) precipitates in the Al-Zn-Mg alloy during homogenization were investigated. Both alloys under as-cast condition with supersaturated, non-equilibrium T(Mg32(Al, Zn)49) phase and impurities phase were displayed. When the homogenization temperatures are below 350 °C, Zn and Mg atoms precipitate......
Effect of homogenization on the microstructure and mechanical properties of the repetitive-upsetting processed AZ91D alloyLi Zhang,Qudong Wang,Wenjun Liao,Wei Guo,Bing Ye,Haiyan Jiang,Wenjiang...">The current research investigates the effect of homogenization on the microstructure and mechanical properties of the AZ91 D alloy processed by repetitive upsetting(RU). Results show that during RU processing......
