Review of Thermomechanical Fatigue Behavior of Austenitic Stainless Steel for Nuclear Power Plant Pipes

摘要： 对过去50年发表的核电管材奥氏体不锈钢热机械疲劳行为研究的文献进行综述。首先对热机械疲劳测试概念的准确定义进行阐述，并对国内外主要的热机械疲劳测试方法标准化的历程进行了系统回顾。对热机械疲劳加载下奥氏体不锈钢循环力学响应的非对称性特征进行描述。对高温疲劳加载下奥氏体不锈钢的主要变形及损伤机理，动态应变时效、氧化和蠕变的典型表现形式、微观作用机理及其与疲劳损伤的交互作用进行了详细分析。依据温度循环的最高值与材料蠕变损伤发生的临界温度间的关系，分别讨论了低温区和高温区内材料的热机械疲劳寿命行为。低温区内材料的主导失效机理是纯疲劳或氧化-疲劳交互作用，高温区内蠕变-氧化-疲劳三者间的复杂交互...
