| 摘 要： | 采用阴极充氢、SSRT缺口拉伸和氢热分析等试验方法,研究了高强度钢42CrMoVNb在不同温度回火状态下的延迟断裂行为,并与常用的机械制造用钢42CrMo进行了对比。结果表明,随着回火温度的升高,试验钢的耐延迟断裂抗力逐渐提高;在相同回火温度下,由于42CrMoVNb钢的强度水平明显高于42CrMo钢,其耐延迟断裂抗力...

| Abstract: | Cathodic charging,notch tension and hydrogen thermal desorption analysis test was used to study the delayed fracture behaviors of high strength steel 42CrMoVNb at different tempering temperatures,which were also compared with commercial structural steel 42CrMo.The results show that the delayed fracture resistance of experimenting steels increases with increasing tempering temperature.Since the tensile strength of 42CrMoVNb steel is higher than that of 42CrMo steel at same tempering temperature,the delayed f... |
