Article Preview

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.
