Paper Title:
Study on Strengthening Mechanism of Cd Additions for AZ31 Magnesium Alloy
  Abstract

The effect of Cd on the microstructure and mechanical properties of AZ31 magnesium alloy has been investigated in this paper. The results indicate that the microstructure of the AZ31 magnesium alloy is refined obviously by adding a little Cd. When 0.7%Cd is added, the alloy is made up of Al-rich α-Mg matrix and the phase of β-Mg17Al12 which distributes and disperses in the matrix uniformly. Cd solid dissolves in the matrix and there is no new phase formed, which contributes to the increase of the impact toughness, Brinell hardness, tension strength and elongation of the experimental alloy by 68.6%,10.3%,9% and 35%,respectively.
