Dislocation and Diffusion Deformation Mechanisms of Ultrafine Grained Materials

Article Preview

Abstract:

Deformation mechanisms of polycrystals as a function of the grain size in the 1nm…1cm interval are studied in this paper. The critical grain sizes are identified. Activity of dislocation and diffusion mechanisms is analyzed. The distribution of deformation in grains with different sizes within the same polycrystal is considered.
