40Cr和45钢形变表面强化复合处理弯曲疲劳性能研究

The Study of Bending Fatigue Property of 40Cr and 45 steel Treated with Combination of Ausform and Case-hardening

本文研究了40Cr和45钢高温形变热处理后进行表面淬火、软氮化以及软氮化加表面淬火复合处理的弯曲疲劳性能,并与其调质后的表而强化以及20CrMnTi和25MnTiBRc钢渗碳的疲劳强度值进行了比较,得出一些重要结果.

This paper deals with the bending faliguc properly of 40Cr and 45 steel treated with high-tempcrature ausform hardening, soft-nitriding, Case-hardening and combinition of them, as compared with the property of carboned 20CrMnTi and 2SMnTiBRe,somc important results were given in the experiments.
