4. Hardness comparison - Wikipedia

   en.wikipedia.org/wiki/Hardness_comparison

   A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .

5. Indentation hardness - Wikipedia

   en.wikipedia.org/wiki/Indentation_hardness

   Indentation hardness tests compose the majority of processes used to determine material hardness, and can be divided into three classes: macro, micro and nanoindentation tests. [2] [3] Microindentation tests typically have forces less than 2 N (0.45 lb f). Hardness, however, cannot be considered to be a fundamental material property.

9. Hardness - Wikipedia

   en.wikipedia.org/wiki/Hardness

   A hardness number is just a semi-quantitative indicator of the resistance to plastic deformation. Although hardness is defined in a similar way for most types of test – usually as the load divided by the contact area – the numbers obtained for a particular material are different for different types of test, and even for the same test with ...
