Abstract

There was studied the deformation of the steel T91 exposed to electron irradiation at different temperatures. The deformation strength decreasing and the hardening ratio as function of relative elongation were defined in continuous irradiation mode. It was established the increasing of the steel plasticity as the result of the electron beam exposition.
