一、前言钢铁材料物理性能检验一般采取抽样检验的方法,而且对试样的几何形状均有一定的要求。试样尺寸的标准化,对于采用电磁学原理来测量钢铁材料的物理性能是必要的前提。常规力学性能的测定,按照技术条件多数要求将试样毛坯进行热处理,然后按GB228-63金属拉力试验法加工成拉伸试样,在材料试验机上测其性能。能否合格,同热处理工艺的正确与否关系极大。热处理质量的
First, the general test of physical properties of steel materials to take the sample test methods, but also the geometry of the sample has certain requirements. The standardization of sample size is a prerequisite for the use of electromagnetics to measure the physical properties of steel materials. The determination of conventional mechanical properties, in accordance with the technical requirements of most of the requirements of the sample blank heat treatment, and then press GB228-63 tensile test method of metal processing into tensile specimens, test the performance of the material testing machine. Whether qualified, with the heat treatment process is very much related to the right or not. Heat treatment of quality
