Abstract：An investigation was made of the effect of the isothermal quenching at dif-ferent temperatures in the martensitic range on the structure and properties of 30CrMnSiNi2A steel.To sum up the results from the tests of stress corrosion,lowcyclic fatigue,fracture toughness,fracture feature and conventional mechanicalproperties,the optimum isothermal quenching regime was ascertained.Experimentalresults show that the superior comprehensive properties of the steel may be ob-tained by treatment of isothermal quenching at 285℃ then tempering at 280℃.It is believed that the lower bainite and residual austenite are the chief factors inimprovement of toughness and plasticity of the steel,however,the tempered mar-tensite is an important factor to ensure its high strength. 收稿日期: 1985-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张百伟 张振芳 李淑清 张兴华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I5/13 1 西北工业大学401教研室,国营峨嵋机械厂,未公开发表资料,1977． 2 潘雅琴;张颂华;张自国;北京航空学院,未公开发表资料,1979． 3 富田惠之;宫本启太;冈林邦夫,铁钢,64(1978) ,759． 4 Judy,R.W.,Jr.;Goode,R.J.,NRL Report,7865 AD-A008 119,(1975) .
