摘要:
粉末冶金颗粒增强铝合金作为工程构件材料使用时经常处于循环载荷条件下，疲劳破坏现象极为普遍。影响粉末冶金颗粒增强铝合金疲劳性能和疲劳寿命的因素较多，但关于疲劳失效方面的报导较少且缺乏概括性的总结。基于此，主要综述了增强颗粒、基体微观结构、温度和应力比对粉末冶金颗粒增强铝合金疲劳性能的影响。总结了疲劳强度、疲劳裂纹扩展与上述因素之间的关系，并详细阐述了这些因素的影响机制。介绍了颗粒增强复合材料疲劳寿命预测方法。最后展望了粉末冶金颗粒增强铝合金疲劳寿命预测的研究趋势。
Abstract:
As a kind of engineering component materials, powder metallurgy particle reinforced aluminum alloys（PMPRAs） are often subjected to cyclic loading in practical application, so the fatigue failure is very common. There are many factors affecting the fatigue properties and fatigue life of PMPRAs. However, the reports about fatigue failure are few and a general summary of the research on fatigue failure is needed. Therefore, the effects of reinforced particles, matrix microstructure, temperature and stress ratio on fatigue properties of powder metallurgy particle reinforced aluminum alloys are mainly reviewed. The relationship between fatigue strength, fatigue crack growth and the above factors are summarized, the mechanisms of these factors are represented in details. Subsequently, the fatigue life prediction methods of particle reinforced composites are introduced. Finally, the further research on the prediction of fatigue life of powder metallurgy particle reinforced aluminum alloys is prospected.
