This paper studied the twinning behavior of AZ31 magnesium alloy in the high cycle fatigue process and the microscopic characteristics of twins, and studied systematically the influence of orientation and fatigue load on twinning in the high cycle fatigue deformation process of magnesium alloy and the role of twins in the fatigue deformation process with the help of metallographic observation, fatigue performance analysis, fracture morphology observation, Transmission Electron Microscope (TEM) and other analysis methods. The results show that twinning could play an important role to the fatigue deformation of magnesium alloy at room temperature, the ratio of twinning varies in different fatigue loading directions, the radio of twinning is the highest for loading perpendicular to the extrusion direction.

主要研究了AZ31镁合金在高周疲劳过程中孪生行为和孪晶的微观特征,并借助金相观察、疲劳性能分析、断口形貌观察、透射电子显微镜(TEM)等分析手段,较系统地研究了取向、疲劳载荷对于对镁合金高周疲劳变形过程中孪生的影响规律以及孪生在疲劳变形过程中的作用,结果表明,镁合金在室温高周疲劳变形条件下,孪晶在疲劳过程中发挥了重要的作用,不同疲劳加载方向上孪晶的发生率有所不同,垂直于挤压方向加载,孪生发生率最高。
