摘要
研究了稀土变质与热处理对白口铸铁的共晶碳化物形貌及冲击韧度的影响。结果表明 :稀土变质及热处理均能改善碳化物的形貌 ,提高其冲击韧度 。
The effect of RE and heat treatment on eutectic carbide morphology and impact toughness of white cast iron was studied.The results show that rare earth modification and heat treatment all can improve eutectic carbide morphology and increase the impact toughness,and both compre hensive result is more noticeable.
