摘要/Abstract

摘要： 以42CrMo钢棒为对象,使用中频感应加热进行调质处理,研究了不同回火温度(500、550、600、650及700 ℃)对42CrMo钢棒组织及力学性能的影响。结果表明,随着回火温度的升高,42CrMo钢的显微组织均为回火索氏体,碳化物由不均匀分布细针状逐渐转变为短棒状,长宽比减小。随着回火温度升高至600 ℃,碳化物转变为弥散分布的颗粒状,650 ℃时颗粒状碳化物出现偏聚,700 ℃时回火索氏体快速粗化,硬度、抗拉强度与屈服强度呈现连续下降趋势,断后伸长率与断面收缩率呈连续小幅度上升趋势。

Abstract: Effect of tempering temperature (500, 550, 600, 650, 700 ℃) on microstructure and mechanical properties of the 42CrMo steel bar was studied by medium frequency induction quenching and tempering. The results show that as the tempering temperature increases, the microstructure of the 42CrMo steel keeps as tempered sorbite. The carbides gradually change from unevenly distributed fine needle shape to short rod shape, and the aspect ratio decreases, then transform into a dispersed granular shape at 600 ℃, and segregate at 650 ℃, coarsen rapidly at 700 ℃. With the increase of induction tempering temperature, the hardness, tensile strength and yield strength show a continuous downward trend, while the elongation after fracture and the percentage reduction of area show a continuous small upward trend.

Key words: 42CrMo steel bar, induction quenching and tempering, tempering temperature, microstructure, mechanical properties
