本文着重介绍用穆斯鲍尔效应分析 GCr15轴承钢在不同热处理工艺条件下所含各相的相对含量和马氏体中的含碳量。同时讨论碳化物对确定残留奥氏体含量的影响。
This article focuses on the analysis of the relative content of the phases contained in the GCr15 bearing steel under different heat treatment conditions and the carbon content in the martensite by using the Munsbauer effect. The effect of carbides on the determination of retained austenite content is also discussed.
