Abstract: The determination of conditions for laser-induced intensification of mass transfer processes in the solid phase of metallic materials was conducted. We studied the process of interdiffusion of Fe and Cu. A laser beam of uniform power density and a pulse frequency of 100, 1,000, and 5,000 Hz was used. The laser radiation was transformed into a uniform light spot with a diffractive optical element, which performed the required focusing. It was determined that for the generalized thermo-dynamic driving force to ensure the mass transfer intensification in non-equilibrium conditions, a necessary condition is the unsteady local deformation caused by laser action.

Keywords: laser action, diffractive optical element, mass transfer, metallic material, texture, sample, vibration rate.
