摘要

为了寻求变形温度、变形量对含钼钢显微组织、先共析铁素体量及其晶粒度的影响规律,利用Gleeble1500热模拟实验机、光学显微镜、XL30扫描电镜和IA32图像分析仪,分析了不同变形量、不同变形温度下含钼钢的组织。结果表明:在一定条件下,随着变形量的增加,显微组织由铁素体+贝氏体转变为铁素体+贝氏体+珠光体;同时先共析铁素体含量及其晶粒度级别均呈现出提高的趋势。

Abstract

The effect of deformation temperature and deformation ratio on microstructure, proeutectoid ferrite content and grain size of steel containing Mo was studied using Gleeble1500 hot simulation experiment machine, optical microscope, XL30 SEM and IA32 image device. The result shows that under the definite condition, with the increasing of deformation ratio, the microstructure is transformed from ferrite+bainite to ferrite+bainite+pearlite and at the same time proeutectoid ferrite content and its grain size are increased.
