A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

Compared to classic testing applications, hardness testing in powder metallurgy needs completely different procedures and parameters. Samples must be prepared well to permit the hardness test 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 penetration ...

This class presents a description of each hardness testing method, along with discussions on how to choose and perform a test, how to read hardness ratings, and how to prevent common errors. Hardness ...
