摘要(Abstract)：

采用QBG-50型高周疲劳试验机对高钴钼不锈轴承钢进行轴向拉压疲劳试验，研究了其在室温和500℃下的疲劳裂纹萌生扩展行为。结果表明：室温条件下试验钢的拉压疲劳极限强度为785 MPa, 500℃条件下试验钢的拉压疲劳极限强度为550 MPa,较室温降低了30.0%。通过扫描电镜对疲劳断口观察发现，室温下试验钢的疲劳裂纹起裂类型为单源起裂，起裂源为驻留滑移带、表面加工缺陷和夹杂物，高温下试验钢的起裂类型为单源起裂和多源起裂，起裂源为驻留滑移带、夹杂物和表面加工缺陷。室温下疲劳裂纹萌生于内部驻留滑移带，而500℃下疲劳裂纹多形成在表面或接近表面的滑移带。拉压裂纹萌生寿命占总寿命的97.88%以上。
