Microstructures and Mechanical Properties of Si and Sb Added Mg Alloy

Open full text 3 citations

Abstract

The effect of Si and Sb on the microstructure and mechanical properties of AM60 magnesium alloy has been studied. The results indicate that Si addition introduces Chinese script type Mg2Si phase at the grain boundary and increases the ultimate tensile property and hardness except the elongation of AM60 magnesium alloy. The Chinese script type Mg2Si phase changes to a fine polygonal shape and the grain sizes decreases by addition Sb. Sb addition increases the mechanical property of the alloy.
