摘　　要：以两种中碳低合金钢为研究对象,采用彩色金相-化学腐蚀法研究经普通淬火、等温淬火和正火处理试样的组织。利用金相显微镜的图像处理系统计算出贝氏体组织的体积分数,用XRD方法测试出残留奥氏体的含量,最后得出马氏体含量。结果表明,利用彩色金相技术定量分析贝氏体钢的多相组织是可行的。Microstructure of two kinds of low-carbon alloyed steels after quenching, isothermal quenching and normalizing was studied with colored metallography-chemico-etching method. Using the image processing system, the fraction of the bainite phase was calculated. With XRD method, the content of the residual austenite was examined. At last, the martensite phase content was obtained. The results show that it is feasible to analyze the multiple phases quantitatively of the bainite steel using the colored metallographic technology.
