摘　　要：总结了变质处理对含铬白口铸铁组织和性能的影响。通过净化合金液,细化基体晶粒,细化碳化物可使铬合金白口铸铁的冲击韧性提高。The effects of various modifying additives and modifying processes on the microstructure and properties of Cralloyed white cast irons were summarized. By purifying the alloy melt, refining matrix grain and carbide, it is possible to increase the impact toughness of the Cr-alloyed white cast iron.
