Abstract

PURPOSE:To measure the change in the hardness of a specimen in the depth direction thereof and to measure the hardness of a multilayer structural material, by calculating the load increase quantity to the unit indentation depth at the arbitrary measuring point of time with respect to the load and indentation depth at the measuring point of time. CONSTITUTION:The load increase quantity P' (P'=dP/dD) to the load P at the arbitrary measuring point of time and the unit indentation depth D at said point of time is calculated while the load applied to a pressure element and the indentation depth thereof after the pressure element is brought into contact with the surface of a specimen. Since the instantaneous hardness of thereof is calculated on the basis of the increase quantity, the change in the hardness of the specimen in the depth direction can be calculated.
