摘　　要：对Mg-Zn-Mn三元镁合金进行了多方向锻造,工艺参数分别为250℃-6P(P为道次),250℃-9P,300℃-6P,300℃-9P。通过力学和电化学实验和分析得出:对于合金性能的影响,温度的改变比打击道次的改变要明显得多,低温下多方向锻造晶粒细化更显著,高温变形后样品电化学腐蚀倾向更低。Multi-directional forging of Mg-Zn-Mn ternary magnesium alloy was carried out. Its process parameters were250℃-6P（P is pass）,250℃-9P,300℃-6P and 300℃-9P respectively. Through the mechanical and electrochemical tests and analysis, it is concluded that for the effects of the properties of the alloy, changing temperature is obvious than changing the passes of blows. The grain refinement of multi-directional forging at low temperature is more remarkable. But electrochemical corrosion tendency of samples after higher temperature deformation is lower.
