Physicomechanical interpretation is proposed for the use of indentation on different scales of structural levels for evaluating the condition of heat-resistant steel 15Kh2MFA(II) after high-temperature static deformation. Analysis of the results is carried out using a phenomenological hypothesis formulated taking account of known features of correlation of hardness and microhardness measurement data with material structural parameters. It is demonstrated by experiment that the sensitivity of indentation methods depends on participation of different material structural levels in deformation.
