Copper crystals with fragmented structure and developed surface in temperature fields


The effect of electrodeposition regimes of copper polycrystalline foils and coatings on their structure, morphology and behavior during subsequent heat treatment is studied. Electrodeposition is carried out with simultaneous mechanical activation of the surface of foils and coatings, which leads both to the materials internal structural changes and to the appearance of features of the surface morphology: the specific faceting of growth terrains, the formation of polyatomic growth steps, and the appearance of crystals (grains) with pentagonal symmetry. The results of changes in the morphology, structure and phase composition of the polycrystalline copper obtained during the heat treatment in oxidizing or inert atmospheres are presented.
