Determination of hardness of ceramic phases of hard alloys, cutting ceramics and cermets

The possibility of determination of macrohardness and microhardness by calculation for carbides, nitrides and borides at any load using the known microhardness according to Vickers or Knupp, as well as the microhardness at the known macrohardness according to Vickers is shown. The hardnesses of a number of phases, not previously given in publications, are calculated.
