Constitutive description for casting magnesium alloy involving void evolution CHEN Bin(陈 斌)1, 2, YUAN Quan(袁 权)1, 2, LUO Ji(罗 吉)1, 2, FAN Jing-hong(范镜泓)1 1. College of Resources and Environmental... University, Chongqing 400044, China Received 23 September 2009; accepted 30 January 2010 Abstract: In order to investigate the effect of microvoids on the mechanical behavior of casting magnesium alloy......
stirring during solidification on the microstructure and corrosion property of AZ61 magnesium alloy was investigated. The corrosion behaviour of AZ61 was studied in 3.5mol/L NaCl by measuring electrochemical polarization. The results show that the permanent-magnet stirring refines the microstructure of AZ61 magnesium alloy, which improves the precipitation amount and distribution uniformity of β......
