Filling analysis for thixomolded process of AZ91D magnesium alloy ZHANG You-fa(张友法), LIU Yong-bing(刘勇兵), CUI Xiao-peng(崔晓鹏), CAO Zhan-yi(曹占义) Key Laboratory of Automobile Materials, Ministry... words: analysis; semisolid; thixomolded; magnesium 1 Introduction Recently, Thixomolding? becomes one of the hottest topics as a kind of lately-developed magnesium alloy process, which combines......
magnesium alloy which consists of α-Mg (the matrix), eutectic phase and β phase (Mg17Al12), as shown in Fig.1. Fig.2 shows the morphology and composition of the inclusion in the alloy. The content... shifts to less negative value. It is suggested that the control trace element by purification is an effective way to enhance the corrosion resistance of AZ80 magnesium alloy.

Hot-compression constitutive relation of as-cast AZ31 magnesium alloy SHI Ti(史褆), YU Kun(余琨), LI Wen-xian(黎文献), WANG Ri-chu(王日初), WANG Xiao-yan(王晓艳), CAI Zhi-yong(蔡志勇) School of Materials...-compression process, the various factors have obvious effects on the deformation behavior of AZ31 magnesium alloy deformation behavior. To understand the hot-compression constitutive relation thoroughly......
finer grains. The magnesium alloy strips with finer grains give X-ray diffraction patterns increased intensities. All the X-ray diffraction peaks correspond to α-phase (Mg) and noγ-phase (Mg17Al12) has... allowed for solidification, which results in a supersaturated solid solution rich in α-Mg. The absence of the brittle γ-phase in the as-cast strip indicates that the plasticity of the magnesium alloy......
