摘　　要：通过对AZ31镁合金采用不同的退火工艺,利用金相显微镜观察、摩擦磨损试验,研究了不同退火工艺对AZ31镁合金显微组织和耐磨性的影响。结果表明,最佳的退火工艺为280℃×80 min。此条件下会形成再结晶组织,使晶粒细化,从而改善耐磨性,材料的耐磨性与前工艺相比,有明显提高。AZ31 magnesium alloy was annealed under different processes, and the effect of annealing process on microstructure and wear resistance was investigated by mean of metallographic microscope and wear test machine. The results show that the optimal annealing process is 280 ℃× 80 min, therefore, the recrystallized microstructure and fine grain can be obtained, and the wear resistance be improved obviously.
