Abstract

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
