摘要

试验研究了HM钢(%:0.48C、5.1Cr、2.0Mo、1.0V、2.0W)和H13钢(%:0.38C、5.1Cr、1.4Mo、1.0V)的组织、冲击韧性和耐磨性。结果表明

HM钢中W、Mo元素含量较H13钢高

存在更多未溶碳化物阻碍奥氏体晶粒长大

细化晶粒

使平均冲击值比H13钢提高35.5%;HM钢高温回火时

马氏体基体弥散析出更多的碳化物

二次硬化效果显著

平均耐磨性比H13钢提高34.8%。

Abstract

The structure

impact toughness and abrasion resistance of steel HM (0.48C

5. 1Cr

2.0Mo

1.0V

2.0W)and steel H13(0.38C

5. 1Cr

1.4Mo

1.0V) have been tested and researched. Results showed that as the con- tent of W and Mo in steel HM was higher than that in steel H13

more undissolved carbides existed in steel HM to hinder growth of austenite grain to get fine grain

the average impact value increased by 35.5% as compared with steel H13; with high temperature tempering

as more carbides dispersed precipitated from matrix of martensite in steel HM and secondary hardening was obvious

the abrasion resistance increased by 34.8% as compared with steel H13.
