Аннотация

Profiles of depth distribution of nickel concentration in the ultrafine-grained molybdenum after isothermal homogenizing annealing and surface irradiation by a pulsed electron beam in a non-melt regime were determined by Auger spectroscopy methods. It was established that the mutual penetration of molybdenum and nickel atoms is activated in the surface layer as a result of electron beam irradiation, and the diffusion regime in the grain boundaries is changed in comparison with that observed under the homogenizing annealing. Indicated changes are shown to be associated with an increase in the dislocation density in the surface layer and the appearance of additional internal stresses caused by the electron beam exposure.
