一、简介用感应加热法快速加热的钢的机械性能比用电炉普通加热的纲的机械性能好。因为前一种钢比后一种钢的奥氏体晶粒度细,回火强度高。本文研究了高强度低合金钢快速回火期间的强度和韧性的变化。
I. INTRODUCTION The mechanical properties of steels rapidly heated by induction heating method are better than those of ordinary heating furnaces. Because the former than the latter steel austenite grain size thin, high tempering strength. In this paper, the changes of strength and toughness during rapid tempering of high strength and low alloy steels were studied.
