Effect of radiation-induced change of mechanical properties of Fe-5 wt.% Mo alloy irradiated with electrons (2 MeV) at room temperature and 400°С has been investigated. Mechanical properties were estimated by Miniaturized

With the purpose of separation of thermal and radiation contributions into the effects, the tests were carried out for specimens annealed in the same thermal conditions (temperature and duration of annealing) just as during irradiation. Thermal annealing and electron irradiation at 400°С is found to bring to multidirectional effects of the alloy strengthening and softening respectively. It is concluded that irradiation suppresses the effect of thermal-induced strengthening and stimulates a softening of the alloy due to more significant changes in the structure and phase composition of it.
