摘要
A micro-hardness measurement method for calculating the hardness of a test sample by pushing an indenter in the test sample and forming an indentation thereon, including: a loading step for extracting load data showing the relationship between load L applied to the indenter and a depth δ to which the indenter is pushed in from the surface of the test sample; an unloading step of extracting unloading data showing the relationship between the load L applied to the indenter after the load is unloaded and the depth δ; a first step of judging, by comparing the unloading data with the load data, the load fluctuation amount from the maximum depth δ0 when unloading the load; and a second step of judging the load at the depth δ1(δ1δ0) when unloading the load or the load fluctuation amount in the vicinity of the depth δ1.
