一、前言 众所周知,钢铁材料是一种具有多型性转变的金属,其内部组织中存在各种不同的组成相,钢铁材料的性能决定于这些相的组成。因此,分析钢铁材料内部的组织组成;研究各相之间的转变规律;掌握合金元素对相变规律的影响,在新材料的研制过程中是非常重要的。 物性测试是利用钢铁材料内部组织中各
First, the preamble As we all know, steel is a metal with a multi-type changes in its internal organization there are different components, the performance of steel materials depends on the composition of these phases. Therefore, it is very important to analyze the microstructure of the steel material, to study the transformation rules between the phases, and to understand the influence of alloying elements on the phase transformation law. Physical testing is the use of steel materials within the organization
