摘要/Abstract

摘要： 通过扫描电镜观察、拉伸及低温冲击试验,研究了不同淬火工艺对含1%(质量分数)Ni的中锰钢组织和性能的影响。结果表明,随着淬火温度升高,试验钢的屈服强度和抗拉强度先增大后减小,随后再逐渐增大,低温冲击吸收能量具有相同变化趋势;中锰钢的最优调质工艺为900 ℃淬火后于600 ℃回火,其屈服强度、抗拉强度及伸长率分别能达到560 MPa、640 MPa及21.8%,-50 ℃ 冲击吸收能量达到270 J,获得了良好的综合力学性能。调质态试验钢在不同淬火温度下均获得了铁素体和回火马氏体组织,随着淬火温度升高,马氏体比例增加,晶粒尺寸逐渐减小。

Abstract: Effect of quenching process on microstructure and mechanical properties of a medium manganese steel containing 1% (mass fraction) Ni was studied by means of SEM observation, tensile test and low temperature impact test. The results show that with the increase of quenching temperature, the yield strength, tensile strength and impact property of the tested steel first increase, then decrease, and then gradually increase. The optimal quenching and tempering process of the tested steel is quenching at 900 ℃ and tempering at 600 ℃, at which the yield strength, tensile strength and elongation can reach 560 MPa, 640 MPa and 21.8%, respectively, and the impact absorbed energy of the tested steel at -50 ℃ can reach 270 J, the good comprehensive mechanical properties can be obtained. The quenched and tempered tested steel obtains ferrite and tempered martensite under different quenching processes, the proportion of martensite increases and the grain size gradually decreases with the increase of quenching temperature.

Key words: medium Mn steel, quenching and tempering, mechanical properties, ferrite, tempered martensite
