Analysis on flow stress of magnesium alloys during high temperature deformation YANG Ya-qin(杨亚琴), LI Bao-cheng(李保成), ZHANG Zhi-min(张治民) College of Materials Science..., %) To find out the flow stress of the different magnesium alloys at various deformation conditions, high temperature compression test was performed in the temperature range of 423-773 K with 323 K......
chamber and "sub zero" systems lead towards an oxidation free and low distortion vacuum heat treatment for a broad range of parts and materials. Short and energy saving processes guarantee a high economic efficiency and environmental compatibility.The "sub zero" system which is integrated into the standard vacuum furnace achieves a heat treatment result with a high conversion of retained austenite......

the influence of the copper content, temperature and time on the evolution of the coarse particles of Al-Zn-Mg-Cu alloys during solidification and heat treatment. The transformation from eutectic... in alloy A2 slows down the diffusion process during heat treatment. Furthermore, the high supersaturation extent of Cu in alloy A2 will provide more Cu solutes to form Al2CuMg and lead......
