摘　　要：研究了稀土、铝复合变质处理对微量、多元低路白口耐磨铸铁组织和性能的影响。试验证明，变质处理可以显著地改变碳化物的形态和分布，使碳化物断网、孤立和尖角钝化从而提高了材料的性能。The paper deals with the influence of RE and Al Complex metamorphosis on the wear resistant with cast iron which contains tiny multielement and low Cr. The test proves that the forms and distrbution of carbides can obviously be changed through the metamorphosis.Because of the broken net, isolation and sharp angle passivation of carbides, the properties of cast iron have been improved greatly.
