Purely as a philosophical observation. It is not possible to measure the hardness of a metal or alloy "as it was" because the act of making a hardness indentation by any method causes displacement of the metal and hence results in work or strain hardening. Therefore the hardness you measure is not actually the one before you made the indentation. Not to worry---all harness values are empirical anyway and we get along quite well by standard methods and reference tables. "Hardness of metals, as the storminess of the seas is easily appreciated but less readily measured." {Prof Hugh O'Neil, "Hardness of Metals and its Measurement," 1950.
