Comparison of International Rockwell C and Vickers Hv 30 Hardness Scales During 1970 and 1971

摘要

The results of comparisons, made over a period of two years, of the standarized Rockwell C scale and Vickers HV30 scale are presented in graphical form. The hardness values in Rockwell C scale and Vickers HV30 scale on the same test blocks are discussed in relation to published hardness conversion tables. (Author)
