Effects of Sr,Y on Microstructure and Mechanical Properities of AZ31 Alloy

XIE Weidong1,2,NING Xu1,WANG Chunguang1,PENG Xiaodong1,2(1.College of Material Science and Engineering,Chongqing University,Chongqing 400045,China;2.National Engineering Research Center for Magnesium Alloys,Chongqing 400044,China)  
The effects of Sr,Y on the microstructure and mechanical properties of metal mold casting AZ31 alloy were investigated by OM,SEM,EDS,XRD and tensile testing.The results show that the grain of AZ31 alloy can be refined by adding a small amount of Sr and a rod-like phase forms along the grain boundaries.While adding slight Y and Sr into AZ31 alloy,the size of α-Mg grain dramaticlly decreases,Al2Y phase precipitates in the grain and β-Mg17Al12 disappears.With the addition of Sr and Y,the tensile strength at ambient and high temperature obviously enhances.
