一、前言碳化物相是黑色金属中的基本相之一,我们在金相检验中往往只研究碳化物相的形貌、分布和性能的关系。对于碳化物的类型及性质一般无法识别。而金属材料中的碳化物类型对金属材料的各种性能有密切联系和影响,因此引起了人们的重视,随着物理测试方法的迅速发展,对碳化物类型的研究越来越多。 First, the preface Carbide phase is one of the basic phase in ferrous metals, we often only study in the metallographic examination carbide phase morphology, distribution and performance of the relationship. The type and nature of the carbide are generally not recognized. However, the type of carbide in metal material is closely related to the various properties of metal materials. Therefore, people pay more attention to it. With the rapid development of physical testing methods, more and more studies on the types of carbides have been carried out.
