- 通过对HB(布氏硬度)、HRB(B标尺洛氏硬度)试验机理及HB与HRB的关系进行分析,提出对ASME(美国国家标准)系列管材的硬度测定应根据管材壁厚进行统一规定的观点.Through the analysis of the test principles of Brinell Hardness (HB) and Rockwell Hardness, B scale (HRB) and the relation of HB with HRB, a proposal has been put forward by the author that the hardness-testing methods of tubes should be unified according to the wall thickness of tubes of ASME series.
- 辊由高级工具钢制成，经过热处理，洛氏硬度超过60，并经镀铬和镜面抛光处理。Rolls machined from high-grade tool steel, which has been treated to a hardness of over 60 Rockwell C and hard chromed, precision ground as well as polished to a mirror surface.
- 结果表明,表面粗糙度对布氏硬度值有重要影响,而洛氏硬度值与表面粗糙度关系不大。It was found that the surface roughness is significant in Brinell hardness testing, but has little influence on Rockwell hardness.
- 本文通过对16种金属材料布氏和洛氏硬度的测试,讨论了表面粗糙度对它们的硬度值的影响。The Rockwell and Brinell hardness of 16 metals were investigated. The effects of surface roughness on the hardness values were discussed.
