摘要

本文通过对含Ｃｒ量在１５％左右，含Ｃ量在亚共晶区变化的铸态高铬白口铁进行混合稀土变质处理研究，认为碳的影响最显著，稀土的影响是明显的。稀土处理可提高韧性、抗弯强度，对硬度影响不大。耐磨性能增加。

Abstract

The metamorphic treating of high-Cr white cast iron containing 12％～16％Cr 2．40％～3．40％C is studied. The experimental results show that the ef-fect of carbon is remarkable and the effect of rare-earth metal is evident. Treating by rare-earth

the toughness

banding strength and wear resistance are raised and there is weak effect on hardness.
