摘　　要：论文分析了化学成份对白口铸铁强韧性影响；设计出二组强韧性低合金白口铸铁；并通过微合金化、金属型铸造、热处理等综合措施，获得了ak10J／cm2～20J／cm2、HRC55－HRC62的强韧性能．This paper studies the effects of chemical composition on the strength-toughness ofwhite cast iron. Two series of Low-alloy white cast iron with strength-toughness are designed in the paper. Thc white cast iron with toughness of ak10J/cm2~20J/cm2 and hardnessof HRC55-HRC62 is produced by means of mircroalloying, metal casting process and heattreatment.
