中文摘要:对马氏体不锈钢2Cr13不同处理状态下进行疲劳性能试验,结果表明:适当降低原淬火后的回火温度以及渗氮表面强化处理,疲劳强度有显著的提高。
英文摘要:The fatigue property experiments of martensitic stainless steel 2Cr13 on different heat treatment conditions were carried out. The results show that, when the tempering temperature decreases and the surface is treated through nitriding, the fatigue strength significantly increases.
