As-cast microstructure of Mg-Al-Zn magnesium alloys ZHANG Jing(张 静), PAN Fu-sheng(潘复生), YANG Ming-bo(杨明波), LI Zhong-sheng(李忠盛) College of Materials Science and Engineering, Chongqing University, Chongqing 400044, China Received 28 July 2006; accepted 15 September 2006 Abstract: The research achievements on as-cast microstructure in Mg-Al-Zn alloy were summarized. Under permanent mould cast......
2012; accepted 25 October 2012 Abstract: The microstructure development in the semi-solid state of AM60B magnesium alloy prepared by strain induced melt activation (SIMA) was described. In the SIMA route, cyclic extrusion compression (CEC) and conventional compression were used to predeform as-cast AM60B, respectively. Partial remelting and thixoforming were also carried out within the semi-solid......
