WebIndentation hardness tests compose the majority of processes used to determine material hardness, and can be divided into three classes: macro, microand nanoindentationtests. [2][3]Microindentation tests typically have forces less than 2 N (0.45 lbf). Hardness, however, cannot be considered to be a fundamental material property. WebJan 15, 2003 · The mechanical behavior of hard and superhard coatings is usually characterized by their hardness, H, effective Young's modulus, E *= E / (1− ν2 ), and elastic recovery, We. These quantities are evaluated from loading–unloading curves measured by microindentation using a microhardness tester.

Webmicroindentation hardness test, it is assumed that the indenta-tion does not undergo elastic recovery after force removal. NOTE 2—Use of the term microhardness should be avoided because it implies that the hardness, rather than the force or the indentation size, is very low. 3.2.5 verifying, v—checking or testing the instrument to intelex teddy bears
