Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...

This film discusses hardness testing methods in engineering, specifically focusing on the Brunell and Rockwell hardness tests. It explains how hardness is measured through indentation and penetration ...

Heat treatment is an essential technique for influencing workpiece characteristics. Several industries focus on reliable part design to avoid breaking parts, e.g. by decreasing material weight and ...
