4. Conclusion A numerical technique and mathematical models are proposed that describe the processes of high-temperature creep and fracture of heat-resistant alloys under thermos-power effects with account for irradiation. On the basis of obtained experimental data, the parameters of material functions of thermal creep model for the considered heat-resistant alloy in the temperature range melt T T (0.607 0.679)   are determined.
