STRUCTURE AND PROPERTIES OF ULTRAFINE GRAINED ALUMINUM COMPOSITE AD31 + TIN
А new approach for preparation of ultrafine-grained aluminum composites using ion-plasma sputtering followed by severe plastic deformation has been proposed in this paper. Transmission electron microscopy has been used for structural characterization of the ultrafine - grained composites. Mechanical properties, wear resistance, corrosion resistance and electrical conductivity were estimated in comparison with the samples subjected to the standard treatment.
