摘要：
This paper demonstrates that spheroidizing treatment greatly affects the microstructure and mechanical properties of the extruded Mg94Zn2.5Y2.5Mn1 (at%) alloy. The extruded alloy with spheroidizing treatment exhibits higher strength but lower yield symmetry than that without spheroidizing treatment. The detailed reasons are given and analyzed.
