摘要
采用金相、ＳＥＭ、ＴＥＭ、ＸＲＤ等手段，研究了钢不同热处理条件下７０Ｃｒ３Ｍｏ的组织对接触疲劳性能的影响，结果表明：７０Ｃｒ３Ｍｏ钢直接淬火＋回火条件下以孪晶马氏体为主的组织的接触疲劳性能高于等温淬火＋回火条件下贝氏体的接触疲劳强度。
The effect of microstructure on contact fatigue property of steel 70Cr3Mo with two kinds of heat treatment has been stu- died by means of optical metallography, SEM, TEM and XRD. The results show that the contact fatigue property of plate marten- site after quenching and tampering is higher than that of the bainite after austempering and tempering.
