Paper Title:
Effect of an Impulse Loading on Localization of Diffusing Atoms in Metals
  Abstract

Distribution and mobility of own and impurity atoms in metals subjected to different loadings: quasi-static plastic strains; quasi-static deformations in combination with impulse; sluggish and fast elastic deformations, including alternating, impulse plastic strains are investigated by methods of an autoradiography, layer-by-layer radiometric analysis and secondary ionic mass spectrometry. The common regularities of migration of atoms at deformation of metals are found, and threshold values of a strain rate, corresponding to change of the diffusion mechanism and localization of penetrating atoms in metal, are determined. The conclusion about the bulk mechanism of substance transfer is made at pulse actions irrespective of temperature of processing.
