摘要

通过在2.8C-31Cr合金中添加Ti、V、Nb、Mo制备多元铬系合金

研究了Ti、V、Nb、Mo的添加对高铬合金碳化物形态、硬度和冲击韧度的影响。结果表明

随着合金元素加入量的增加

高铬合金凝固组织中碳化物尺寸先细化到粗化

硬度和冲击韧度先增加后降低。加入0.4%的Ti、0.4%的V、0.4%的Nb、0.4%的Mo时

高铬合金的铸态组织和综合力学性能最好

硬度（HRC）为58.9

冲击韧度为11J·cm-2。

Abstract

Effects of Ti、V、Nb、Mo on the morphology

hardness and impact toughness of carbides in high Cr alloy containing 2.8%carbon and 31.0%chromium were investigated.The results show that with the increase of alloy contents

the carbides size is gradually refined firstly and then coarsened

and hardness and impact toughness are increased firstly and then decreased.When the amounts of alloy elements are 0.4%Ti、0.4%V、0.4%Nb、0.35%Mo

the hardness and comprehensive mechanical properties exhibit desirable

where hardness and impact toughness reach up to 58.9HRC and 11J·cm-2

respectively.
