Influence of conditions of friction indentation loading of some metals on the microhardness scale effect

A new approach explaining the microhardness dependence on indentation load is pro- posed. It is assumed that the scale effect of microhardness is due to stage pattern of plastic strain and to gradual transition from the dislocation strain to the rotation one according to increasing force of indent...
