摘　　要：设计了合适的膨胀管用双相钢的化学成分,研究了淬火温度对双相钢组织和力学性能的影响。结果表明,随淬火温度升高,马氏体体积分数逐渐升高,从而导致屈服强度和抗拉强度升高。淬火温度为820℃时,膨胀管用双相钢可获得最佳的综合性能。Suitable chemical composition of dual phase steel for expansion pipe designed. Effects of quenching temperature on microstructure and mechanical properties of dual phase steel were investigated. The results show that with quenching temperature increasing, the volume of martensite increases which leads to tensile strength and yield strength increase. The best mechanical properties of dual phase steel for expansion pipe can be obtained when queched at 820 ℃.
