Higher hardness is related generally related to higher strength, which in turn is related to its structure. The Rockwell test uses a small steel sphere for the indenter of a diamond cone for harder ...

Each test establishes the depth to which the indenter will sink into the material, at a pre-defined load, within a specific time period. While the Rockwell and Brinell tests mostly apply to metals and ...

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 ...
