高温应变时效对P92钢高温低周疲劳性能的影响
Influence of High Temperature Strain Aging on High Temperature Low-Cycle Fatigue Properties of P92 Steel
摘 要
分别在应力与应变控制下对P92钢进行550℃高温低周疲劳试验，研究该钢在不同应变幅（0.2%~1.0%）和应力幅（280~350 MPa）下的疲劳行为；对P92钢进行不同预拉伸应变（0~4%）和温度（250~350℃）下的应变时效处理后，研究该钢的高温拉伸与低周疲劳性能。结果表明：在应变控制下，P92钢的应变与疲劳寿命关系符合Manson-Coffin方程，在低应变幅（低于0.7%）下P92钢出现先循环硬化后循环软化现象；在应力控制下，应变与疲劳寿命关系不遵循Manson-Coffin方程，高应力幅（350 MPa）下P92钢出现先循环硬化后循环软化现象；应变时效处理可提高P92钢的屈服强度，且高温拉伸曲线出现Portevin-Le Chatelier屈服效应；应变时效处理后P92钢在应力控制下的应变与寿命关系不遵循Manson-Coffin方程，且其低周疲劳寿命大幅降低。

Abstract
The fatigue behavior of P92 steel under different strain amplitudes (0.2%-1.0%) and stress amplitudes (280-350 MPa) was studied by high temperature low cycle fatigue tests at 550 ℃ under stress and strain control, respectively. P92 steel was subjected to strain aging treatment at different prestrains (0-4%) and temperatures (250-350 ℃), and then the high temperature tensile and low cycle fatigue properties were studied. The results show that the relation between strain and fatigue life of P92 steel conformed to Manson-Coffin equation under strain control, and the phenomenon of cyclic hardening and then cyclic softening appeared in P92 steel at low strain amplitudes (below 0.7%). The relation between strain and fatigue life did not follow Manson-Coffin equation under stress control, and the phenomenon of cyclic hardening and then cyclic softening appeared in P92 steel under a high stress amplitude (350 MPa). The strain aging treatment could improve the yield strength of P92 steel, and the high temperature tensile curve showed a Porevin-Le Chatelier yield effect. The relation between strain and life of P92 steel after strain aging treatment under stress control did not follow Manson-Coffin equation, and the low cycle fatigue life greatly decreased.
