摘要/Abstract

摘要： 研究了GCr15轴承钢在单一温度场和磁-热耦合场条件下球化退火时离异共析转变过程中碳化物的析出行为。采用扫描电镜观察不同条件下析出碳化物的形貌,使用维氏硬度计测试不同条件下试样的硬度。结果表明,脉冲磁场有利于GCr15轴承钢离异共析转变过程中碳化物的形成,析出碳化物的等效直径由0~0.2 μm长大到0.6~0.8 μm。动力学分析认为,磁-热耦合场促进碳原子扩散,加速碳化物的析出。

Abstract: Carbide precipitation behavior of the GCr15 bearing steel during the divorced eutectoid transformation process of spheroidizing annealing under single temperature field and magnetic-thermal coupling field was studied. The morphology of carbide precipitated under different conditions was observed by using scanning electron microscope, as well as the hardness was tested by Rockwell hardness tester. The results show that the pulsed magnetic field is beneficial to the formation of carbides during the divorced eutectoid transformation of the GCr15 bearing steel, and the equivalent diameter of the precipitated carbide grows from 0-0.2 μm to 0.6-0.8 μm. Kinetic analysis shows that the magnetic-thermal coupling field promotes the diffusion of carbon atoms and accelerates the precipitation of carbides.

Key words: GCr15 bearing steel, magnetic-thermal coupling field, divorced eutectoid transformation, precipitation of carbides
