Effect of Rare Earth Elements on Microstructure and Mechanical Properties of AZ91D Alloy

Abstract:

Rare earth Y、Gd、Nd were added to improve the tensile strength, elongation, hardness and microstructure of AZ91D magnesium alloy in this study. The investigation had been undertaken by 8 GWU type resistance furnace, RGM - 50 electronic machine , Vickers ,etc. Results show that a moderate amount of composite adding rare earth can effectively improve the tensile strength of AZ91D alloy, elongation, hardness and the organizational structure, as a rare earth content increased after the first performance decline. When rare earth content is 1.8%, the highest tensile strength up to 276.58mpa, 8.3% elongation. When rare earth content is 2.4%, the hardness is up to 99.36 HV1.96.
