摘 要: 对近年来有关镁合金疲劳的研究进行了总结,考察了材料性质、腐蚀介质、高温环境等多种因素对镁合金疲劳性能的影响,并对裂纹萌生及扩展方式进行了分析,归纳了提高镁合金疲劳性能的方法——改善材料质量及表面强化处理或涂层处理,对镁合金疲劳性能的研究进行了展望。 This paper represents the studies on the fatigue of magnesium alloys in recent years.The influ- encing factors of the fatigue behavior of magnesium alloys,which are related to material,corrosive media and elevated temperature,etc,are discussed.The crack initiation and crack propagation are also analysed.The strengthening methods can be used to the quality improvement of bulk material,mechanical surface hardening treament and surface coatings.In addition,the prospect of fatigue of magnesium alloys is discussed.
