硬度试验是材料机械性能的基本试验,其中最广泛采用的是布氏硬度测定法。它是在规定的试验条件下把钢球压入试件来进行测定的,并把压痕的单位表面积上所承受的压力(kg/mm~2)规定为试件的布氏硬度值。现在,一些单位开展了对用测深度方法求材料布氏硬度的研究和试验。本文也想就这个问题发表一些看法。理论分析从瑞典人布列聂尔在1899～1900年间提出布氏 Hardness testing is a basic test of the material’s mechanical properties, of which Brinell hardness is the most widely used. It is determined under the test conditions pressed into the test piece to determine the ball, and indentation per unit surface area under the pressure (kg / mm ~ 2) is defined as the Brinell hardness value of the specimen. Now, some units have carried out research and tests on the Brinell hardness of materials by means of depth measurement. This article also wants to make some comments on this issue. Theoretical analysis Propagation of Brinell was proposed from Bremen, the Swedish, between 1899 and 1900
