金属材料在研制、生产和使用中经常会遇到各种各样的缺陷,由于缺陷的存在往往会导致废品的产生或机件的早期失效。正确地分析缺陷成因,是防止和消除缺陷的关键,因此缺陷分析已成为测试分析学科中的一个重要组成部分。 就分析方法而言,金相分析是一个最基本的方法,当今,随着近代物理测试技 Metal materials are often encountered in the development, production and use of a variety of defects, due to the presence of defects often lead to the production of scrap or mechanical failure of the early. Correctly analyze the cause of defects is the key to prevent and eliminate defects, defect analysis has become an important part of the discipline of test analysis. In terms of analytical methods, metallographic analysis is a basic method, and today, with the modern physics testing technology
