Abstrakt: Conclusions Reactor irradiation of titanium and its a-phase alloys containing3He and irradiation with4He ions leads to increased strength and reduced plasticity in the temperature range 20–400°C. The influence of the two types of irradiation upon these materials is similar. At 20–600°C the irradiated materials conserve an adequate plasticity reserve (d>6%). Viscous destruction of the initial and irradiated samples of the materials examined takes place in mechanical testing. At the temperature (500–600°C) at which recrystallization of nonirradiated materials begins, total recovery of the strength properties and noticeable recovery of the plasticity are observed in the irradiated samples. Titanium alloys are inclined to high-temperature radiation-induced embrittlement to a lesser degree than austenitic stainless steels.
