摘要/Abstract

摘要： 组织调控是优化低合金高强钢力学性能的常用方法。通过透射电镜(TEM)对30CrNi3MoV钢淬火配分后的组织进行分析,同时采用单轴拉伸测试30CrNi3MoV钢的力学性能。结果表明,淬火配分处理后30CrNi3MoV钢的组织由马氏体、贝氏体及少量残留奥氏体构成。配分温度影响组织中碳化物尺寸和各相的相对含量及性能。

关键词: 淬火配分, 微观组织, 贝氏体, 碳化物, 力学性能

Abstract: Microstructure control is a commonly used method to optimize the mechanical properties of low alloy high strength steels. The microstructure of the 30CrNi3MoV steel was investigated by TEM, and the mechanical properties were tested by uniaxial tensile test. The results indicate that the quenching and partitioning treatment leads to the formation of a multiphase structure composed of martensite, bainite, and a minute quantity of retained austenite. The differences in carbide size, the relative content of different phases, and the finial mechanical properties can be attributed by the different partitioning temperatures.

Key words: quenching and partitioning, microstructure, bainite, carbide, mechanical properties
