diffractometer. Then the effect of homogenization temperature on microstructure and mechanical properties of the alloy was studied. The hardness of samples under different homogenization temperatures was measured. The results show that, the alloy is composed of α phase, β phase, Mg17Al12 and AlLi. RE added into the alloy is solved in α phase and β phase completely. After homogenization heat treatment......
