摘要

The microstructures and mechanical properties of Mg-3.0Nd-1.5Gd-0.25Zn-0.5Zr new casting magnesium alloy were investigated. It is found that the microstructure of the as-cast experimental alloy is composed of near equiaxed α-Mg matrix and (α-Mg+Mg ₁₂Nd) eutectic structure distributed along the grain boundary. The optimized aging process parameters were determined by investigating age hardening response of the experimental alloy. The results show that the room temperature yield strength of the experimental alloy after T6 heat treatment is apparently superior to that of ZM6 commercial alloy. In addition, the high temperature tensile strength, yield strength and the creep resistant of the experimental alloy are obviously superior to those of the ZM6 alloy.
