- 通過對HB(布氏硬度)、HRB(B標尺洛氏硬度)試驗機理及HB與HRB的關係進行分析,提出對ASME(美國國家標準)系列管材的硬度測定應根據管材壁厚進行統一規定的觀點.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.
- 輥由高級工具鋼製成,經過熱處理,洛氏硬度超過60,並經鍍鉻和鏡面拋光處理。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.
- 結果表明,表面粗糙度對布氏硬度值有重要影響,而洛氏硬度值與表面粗糙度關係不大。It was found that the surface roughness is significant in Brinell hardness testing, but has little influence on Rockwell hardness.
- 本文通過對16種金屬材料布氏和洛氏硬度的測試,討論了表面粗糙度對它們的硬度值的影響。The Rockwell and Brinell hardness of 16 metals were investigated. The effects of surface roughness on the hardness values were discussed.
