摘要/Abstract

摘要： 采用光学显微镜、SEM、TEM、万能试验机等对汽车用22MnB5钢150～300 ℃不同温度回火后的组织与性能进行研究。结果表明,22MnB5钢经淬火+回火处理后,组织主要为回火马氏体,在透射电镜下观察到明显的第二相析出,具有良好的抗塑性变形能力。随回火温度的升高,过饱和α相发生回复且析出碳化物,力学性能逐渐下降。在试验温度范围内,150 ℃时22MnB5钢的力学性能达到最佳,抗拉强度与硬度分别为1583 MPa和48 HRC。

Abstract: Microstructure and properties of 22MnB5 steel for automobile after tempering at 150-300 ℃ were studied by means of optical microscope, SEM, TEM and universal testing machine. The results show that after quenching and tempering, the structure of 22MnB5 steel is mainly tempered martensite, and obvious second phase precipitation is observed under transmission electron microscope, which has good plastic deformation resistance. With the increase of tempering temperature, supersaturated α phase recovers and precipitates carbides, and the mechanical properties gradually decrease. In the tested temperature range, the mechanical properties of the 22MnB5 steel reach the best at 150 ℃, and the tensile strength and hardness are 1583 MPa and 48 HRC respectively.

Key words: steel for automobile, CCT curves, martensite structure, tensile strength, dislocation, second phase
