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 ...
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 ...
• 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 ...
