摘要：
Presented investigations allowed revealing the correlation between microhardness and the characteristics of strength of heat-resistant steel 15Kh2MFA(II). The sensitivity of the indentation methods is shown to be dependent on the degree of involvement of structural levels in the process of deformation. At the initial stage, this is the intragranular sliding, at the next stage shear of grains and grain conglomerates, and their self-coordinated propagation in the steel. On the one hand, this allows attaining greater macrodeformation, and, on the other hand, does not cause the ultimate exhaustion of the material plasticity at the macrolevel.
