摘要
综述了铝合金材料的疲劳行为研究进展.介绍了铝合金材料的疲劳裂纹萌生机制和特性、裂纹扩展规律及其扩展阶段的研究进展,裂纹疲劳行为的影响因素和微观机制方面的最新研究进展,最后从裂纹萌生和扩展机制以及微观机制等方面提出了铝合金疲劳行为的研究趋势.
The research progress of fatigue behaviour for aluminum alloys was reviewed. The studies on crack initiation mechanism and properties, the law of crack propagation and stages of growth, the latest progress on effect factors and micro-mechanism of fatigue behavior were summarized. Then, development trend of fatigue research was elaborated from aspects of crack initiation and propagation mechanisms and micro-mechanism of aluminum alloy materials.
