一前言布、洛、维氏硬度试验是测定钢的硬度的三种常用方法。布氏硬度(HB10/3000)、洛氏(C标尺)硬度(HRC)和维氏硬度(HV)在数值上并无严格的理论对应关系,但可以根据大量试验数据找出它们之间的互换规律。国家标准GB1172-74提供了描述钢的HB10/3000、HRC、HV之间对应关系的有效数表,若能找到它们之间简便、精确的直接互换经验公式,则对
A foreword cloth, Luo, Vickers hardness test is to determine the hardness of the three commonly used methods. Brinell hardness (HB10 / 3000), Rockwell (C scale) hardness (HRC) and Vickers hardness (HV) in the numerical and no strict theoretical correspondence, but can be based on a large number of test data to find out the interaction between them Change the law. The national standard GB1172-74 provides a valid number table that describes the correspondence between steel HB10 / 3000, HRC and HV. If we can find a simple and accurate empirical formula for exchanging them directly,
