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. barra grande bahia marau
