Mechanical behaviour of Al/Al2O3 composite in pseudo-semi-solid state during isothermal compression CHENG Yuan-sheng(程远胜), LUO Shou-jing(罗守靖) School of Materials Science and Engineering... in the pseudo-semi-solid state was studied by isothermal compression tests. The results show that the values of peak stress obviously decrease with increasing temperature and decreasing strain rate......
. In the present work, the microstructure evolutions of ZK60+RE magnesium alloys formed by compression and equal channel angular extrusion (ECAE) during isothermal holding in the semi-solid state... isothermal holding in the semi-solid state. According to the above results, the initial grain size of ECAE formed alloys is finer than that of compression formed alloy in the semi-solid state. This can......
Taper barrel rheomoulding process for semi-solid slurry preparation and microstructure evolution of A356 aluminum alloy ZHANG Fan(张 帆), KANG Yong-lin(康永林), YANG Liu-qing(杨柳青), DING Rui-hua(丁瑞华... rheomoulding (TBR) machine for light alloy semi-solid slurry preparation was introduced. The semi-solid slurry was obtained from the intense shearing turbulence of the alloy melt in the cause......
at a higher copper level. The typical micrographs of semi-solid castings after a T7 treatment are shown in Fig.7 for Alloy-3 and Alloy-4. It can be seen that Alloy-3 with 4.4% copper has a higher...
