Microstructural stability and mechanical properties of the system V-Nb-Ta-Ti under helium ion irradiation
The purpose of this work is to study the effect of irradiation with low-energy helium ions with an energy of 40 keV on the structural-phase state of multicomponent solid solutions based on V-Nb-Ta-Ti. This type of irradiation at fluence of 2×1017 He/cm2 make it possible to simulate the effects occurring in a nuclear reactor. since during its operation, a large number of neutrons are released, causing nuclear reactions in the material with the formation of inert gases. As a result of the work carried out, it was found that all alloys of the system belong to equiatomic single-phase solid solutions and show a greater value of deformation of the crystal lattice and stress after irradiation compared with pure vanadium. It has been proposed that increasing the number of elements in the V-Nb-Ta-Ti system reduces the mobility of defects created by irradiation, which leads to the formation of smaller clusters and an increase in microdeformation.
