| 摘 要： | 比较了三种WC/钢烧结复合材料在相同的热处理条件下 ,经锻造与未锻造两种不同状态的冲击韧性值 ;研究了锻造对这类脆性材料冲击韧性的影响。结果表明 ,锻造使材料的冲击韧性大幅度提高。原因是锻造使材料组织中大块硬质相“碎化” ,WC粒子的形态、分布状况和钢基体的密度、显微组织结构发生变化的结果。

| Abstract: | In this paper ,the impact toughness values of three kinds of forged or non-forged WC/steel matrix composites under same heat treatment condition are compared and studied ,the influences of forging on impact toughness of these brittle materials are studied,too It is shown that forging makes a k values increase greatly, which results from that forging brings about "breaking up"of big hard phases, and the distribution and configuration of WC phase and the density and microstructure of steel matrix happen to change |

| Keywords: | forging WC/steel matrix composite hard phase steel matrix impact toughness |
