Influence of surface roughness on load dependence of microhardness.

open access: yesJournal of the Society of Materials Science, Japan, 1986
In order to investigate the influence of surface roughness on load dependence of microhardness of annealed structural rolled steel and carbon steel, hardness tests were made by changing the grade of surface roughness as a parameter. The results obtained were analyzed by means of the analysis of variance.The main results obtained were as follows;(1 ...
