摘要
利用高频电阻感应加热自冷淬火方法对４５、４０Ｃｒ和３５ＣｒＮｉ３Ｍｏ钢进行了实验，获得了仿形性淬火带，硬度可达ＨＲＣ５４～５９。金相检验和透射电镜观察，淬硬带主要是回火板条马氏体，４０Ｃｒ钢个别区域有片状马氏体，４５钢有少量的下贝氏体，试件淬火后基本不变形，也无需回火。
The experiments were made in 45,40Cr and 35CrNi3Mo steels by using the method of surface self-cooling hardening with high frequency induction and resistance heating.A hardened imitative band of HRC 54～59 was obtained. By the observation with the metalloscope and TEM,the hardened band consists mainly of tempered lath martensite,some plate martensite was found in the partial zone of 40Cr steel,and small amount of lower bainite in the partial zone of 45 steel. Quenched samples were hardly deformed and no temper was requited.
