【摘要】

：

由于镍基高温合金的高温拉伸强度、高温蠕变抗力良好以及抗高温疲劳和热腐蚀性能优异，因此被广泛地用来制作在严苛的工作环境如航空、动力、石化等部门中需要承受高温、高速等的关键零部件。这些高温的零部件在使用的过程当中主要的失效形式之一为高温低周疲劳。本文分别在650℃和760℃温度下对Inconel 625合金的应变控制条件下的低周疲劳行为进行了研究，以期为Inconel 625合金的抗疲劳设计提供更为可

贝氏体车轮循环硬化与接触疲劳性能关系研究

承受循环载荷的材料会发生性能改变。轮轨接触条件下，车轮亚表面应力、应变、残余应力随循环周次而变化。有研究表明，普通车轮钢在服役过程中存在明显的循环软化现象，亚表面强度下降，材料塑性变形，引起亚表面裂纹的萌生与扩展，接触疲劳剥离。重载条件下，轮轨磨损加剧，接触损伤的几率增加，使车轮掉块、剥离等失效几率增大。
