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%。
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
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.
