With the unloading compliance method for inspecting the fatigue crack length and usingthe elastic-plastic fracture mechanics parameter △J as the driving force for low- cycle fatiguecrack growth,the crack growth rate of HG60RA steel at room temperature and at 400℃have been studied.
用卸载柔度法检测疲劳裂纹长度技术,以弹塑性断裂力学参量△J作为低周疲劳裂纹扩展速率驱动力,研究了HG60RA钢在常温和400℃下的低周疲劳裂纹扩展速率,得到了HG60RA钢在常温下和400℃时的da/dn-△J关系,试验结果表明,HG60RA钢在400℃时的低周疲劳裂纹扩展速率要比其常温下的低,这一结果对带缺陷运行的锅炉压力容器安全性评估和寿命预测提供了依据。
2) by unloading compliance method were summarized.
