Abstract: The effect of electron irradiation on the evolution of the structure and creep of the samples Zr1Nb alloy of industrial production and samples obtained by the IPD method were studied. It was shown that irradiation with electrons with a dose not exceeding D = 5∙1019 сm–2 does not affect the plastic deformation mechanisms of the industrial Zr1Nb alloy, as a result of which its high thermomechanical and radiation stability is maintained. Irradiation by electrons with an energy of E = 10 MeV and doses of D = 6∙101… Show more

The review presents the most significant scientific results obtained at the NSC KIPT NAS of Ukraine during low-temperature studies of the physical and mechanical properties of a wide range of metals and alloys over the period from the second half of the 30 s of the 20th century to recent years. During this period, a school in the field of physics of strength and plasticity was formed at the Institute, at the origins of which were I. V. Obreimov, R. I. Garber, V. I. Startsev, V. I. Khotkevich, B. G. Lazarev, and I. A. Gindin. As a result of the studies of these famous scientists, their students and followers, fundamental concepts in the field of low-temperature physics of strength and plasticity of solids and cryogenic materials science have been developed. The relevance of the results obtained is also confirmed by the development of modern cryogenic and aerospace engineering, nuclear and hydrogen energy, electronics, etc.

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.
