The effect of electrons irradiation with an energy of E = 10 MeV and a dose of D = 5·1019 сm–2 on the structure evolution and creep of alloy VT1-0 in initial and nanostructured states obtained by the IPD method has been stud-ied. It is shown that, the deformation nanostructure of VT1-0 is resistant to subsequent deformation under creep conditions at T = 20 °C and is destroyed at T = 350 °C due to the development of recrystallization processes. Irradi-ation by electrons with an energy of E = 10 MeV and a dose of D = 5·1019 сm-2 has slightly effect on the mechanical characteristics of VT1-0, both in initial and nanostructured states, but leads to the conservation and stabilization of the nanostructure during creep at T = 20 °C and to the deceleration of the process of structure transformation at T = 350 °C as a result of a decrease in the level of internal stresses.
