Paper Title:
Microstructure and Mechanical Properties of AZ81 Alloy with Gd
  Abstract

The effect of Gd(gadolinium) on the microstructure and mechanical properties of aged AZ81 magnesium alloy were investigated. The results showed that 2wt.%Gd addition results in the obvious refinement of grain size, the decrease of β-Mg17Al12 phase and the formation of Al2Gd phase, and improves the mechanical properties of AZ81 alloy at room and high temperature. After the addition of 2wt.%Gd, the tensile strengths are enhanced from 203.2MPa to 249.3MPa at room temperature and from 157.2MPa to 197.3MPa at 150°C. Meanwhile, the elongations are increased.
