Effect of Si on the Microstructure and Mechanical Properties of Mg-2Sb Alloy

Abstract:

In the present work the effects of Si (0.5, 1, 1.5 wt%) on the as cast microstructure of Mg-2Sb alloy have been investigated. Si addition forms new Mg-Sb-Si ternary compound in Mg-Sb alloys besides the morphology of Mg₃Sb₂ changes from needle to chinese scripted and polygonal shaped Mg-Sb-Si ternary compound. The improved room temperature tensile properties are obtained with Mg-2Sb-1Si alloy which is due to the presence of polygonal shaped Mg-Sb-Si ternary compound.
