摘　　要：文章研究了AZ80合金平面变形后的常温抗拉强度的变化规律。结果表明,当变形量超过某一临界变形量(1.39)时,开始发生动态再结晶,并随变形量的增加,抗拉强度增大。在变形温度250℃而变形量达到2.30时,强度最高,可以达到305MPa,此时复合强化效果最好,比均匀化处理后强度提高了50%。The variation law of tensile strength at room temperature after AZ80 alloy plane deformation was studied in this paper. The result indicated that when the deformation exceed to a critical point 1.39 start to crystallize again. And with deformation increasing the tensile strength become larger. When the deformation temperature reached 250°C and the deformation reached 2.30, the intensity is the highest Which arrived 305MPa. At the same time complex strengthening effect is the most conspicuous, which is 50% higher than the effect of equality treatment.
