Creep Properties of Mg-12Gd-3Y-1Sm-0.5Zr Alloy

Abstract:

The Mg-12Gd-3Y-1Sm-0.5Zr (wt.%) alloy was prepared. After solution and aging treatment, the microstructure and mechanical properties of alloy was investigated. The results show that the experimental alloy is mainly composed by α-Mg matrix and Mg₅Gd, Mg₂₄Y₅, Mg₄₁Sm₅ phase. The experimental alloy has excellent creep properties at 200-300°C/50-70MPa.
