• Engineers can use hardness testing to verify the composition or heat-treatment history of materials. • Rockwell, Brinell, Vickers, and Shore are common hardness tests. Their use depends on the ...

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 ...

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 ...

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 ...
