摘要:

使用自主搭建的高温超声疲劳实验系统在常温和600℃进行CrMoW转子钢1×10¹⁰周次超高周疲劳实验, 研究了CrMoW转子钢在工作温度下的超高周疲劳性能。结果表明: 在600℃和常温下转子钢的S-N曲线均呈连续下降型, 试件在10⁹周次后仍发生疲劳断裂。在常温实验条件下疲劳寿命小于1×10⁷周次试件的裂纹多萌生在表面, 而高于1×10⁷周次的多以内部萌生为主。在高温实验环境下裂纹也在内部夹杂处萌生, 且裂纹萌生方式对疲劳寿命没有决定性作用。鱼眼定量分析结果表明, CrMoW转子钢在600℃和常温下裂纹扩展的应力强度因子门槛值分别为3.4 MPam^1/2和1.0 MPam^1/2。

Abstract：

The fatigue properties of CrMoW rotor steel were investigated by a high temperature ultrasonic fatigue system. Fatigue tests of CrMoW rotor steel up to 1×10¹⁰ cycles had been conducted at room temperature and 600℃ respectively. Results reveal that the type of S-N curves present continuously descending at room temperature and 600℃. Fatigue fracture occured over 109 cycles. Fractograph of specimens show that Crack initiate mainly from the surface for the specimens that fatigue life is less than 1×10⁷ cycles, but crack initiate mostly from inclusions for those that fatigue life is greater than 1×10⁷ cycles at room temperature. It is found that crack can also initiate at inclusions, but the modes of crack initiation do not play a decisive role for the fatigue life at high temperature. Threshold values of fatigue crack growth obtained by measuring the size of fisheye are 3.4 MPam^1/2 and 1.0 MPam^1/2 at room temperature and 600℃ respectively.

Key words： metallic materials rotor steel high temperature very high cycle fatigue inclusion initiation threshold value of crack growth
