Abstract To obtain a correct estimate of the microhardness dependence on the size of nanocrystals, the microhardness of amorphous-nanocrystalline samples with the same fraction of the crystalline phase and the same composition of the amorphous matrix but different sizes of nanocrystals was studied. It is shown that the dependence of microhardness on the nanocrystal size in the size range from 5 to 15 nm obeys the inverse Petch-Hall law and corresponds to different mechanisms of interaction nanocrystals with shear bands.
