Abstract
Mass transfer in iron and nickel stimulated by pulsed laser radiation is studied by the radioactive isotope method. New experimental results are obtained and an analysis in terms of kinetic equations is given. It is shown: (a) exposure of the metal surface to high intensity pulsed laser radiation leads to an accelerated atomic migration into the sample; (b) an effective retardation, the value of which depends upon the presence of crystalline defects in metals has an essential influence on the atomic migration rate stimulated by the laser; (c) multiple laser loading results in a concentration maximum formed inside the sample, the depth displacement of which depends upon the energy of light flux and the number of pulsed loadings.
