摘要
综述了压铸镁合金高温蠕变的失效形式及机理 ,结合汽车用镁合金部件的实际制备 ,分析和讨论了提高压铸镁合金抗高温蠕变性能的方法 ,提出了在开发耐高温蠕变镁合金时应注意的问题。
The creep fatigue mode and mechanism of die cast Mg-Al alloys at high temperature are summarized,and the methods for increasing the high temperature creep resistance of die cast Mg-Al alloys are analyzed and discussed in this paper. According to the fabrication of magnesium parts used in automobile, The problems, which should be focused in developing the high temperature creep resistant magnesium alloys, are also brought forward.
