摘　　要：为了满足气缸套的高爆发压力,对材料的强度和弹性模量有了更高的要求,因此进行了灰铸铁的合金化及热处理试验研究,获得了合适的化学成分和热处理工艺;使灰铸铁的抗拉强度超过600 MPa,弹性模量大于140 GPa。In order to meet the high burst pressure of cylinder liner,the strength and elastic modulus of the material have higher requirements,so the alloying and heat treatment of gray cast iron are studied,and the appropriate chemical composition and heat treatment process are obtained.Hence make the tensile strength of gray cast iron exceed 600 MPa and the elastic modulus exceed 140 GPa.
