摘　　要：研究了回火温度对65Mn钢组织及扭转性能的影响。结果表明:低温回火时65Mn钢能获得较高的抗扭强度,且抗扭强度随回火温度上升而越来越小;综合比较,380℃回火时65Mn钢能获得优良的扭转性能。Effect of tempering temperature on microstructure and torsional strength of 65Mn steel was studied. The results show that higher torsional strength can be obtained at low tempering temperature. With the tempering temperature increasing, the torsional strength is decreasing. The tempering temperature 380 ℃ is the optimum tempering temperature of 65Mn steel to attain high torsional strength.
