Abstract Results are presented of the experimental examination of the viscoplastic properties of 15Kh2MFA, 15Kh2NMFA, and VK2 (KP-100) heat-resisting steels simulating radiation-embrittled 15Kh2NMFA steel, at different ratios of the main stresses in the temperature range 20–350°C, carried out using a specially prepared method. The experimental results are used to draw conclusions according to which the generalized quasistatic (equilibrium) deformation diagram, obtained at a strain rate tending to zero, is invariant to the type of stress state, and also that the toughness factors of the examined steels are invariant to the type of stress, state and cumulated plastic strain in the entire temperature range examined.
