Modification of the surface of the VT6 alloy by plasma of electric explosion of a conducting material and by electron beam

The results of investigations into the phase composition, structure, and properties of the surface layer of the VT6 titanium alloy subjected to combined treatment consisting of alloying by the plasma of an electric explosion of a graphite fiber with a charge of the SiC powder and subsequent exposure by a high-intense electron beam are represented. As a result of such treatment, a multiphase surface layer with a submicron and nanosize structure forms with the microhardness manifold exceeding its value in the sample volume.     

Nanotechnology for copper and copper alloys

This article surveys and analyzes the literature data on nanotechnologies for copper and copper alloys. It describes the main methods used to obtain nanomaterials, including powder metallurgy, crystallization from the liquid state with a controlled rate of cooling, intensive plastic deformation, dispersion hardening, and dispersion strengthening with internal oxidation. Preference is given to nanophase materials in the discussion. __________ Translated from Metallurg, No. 8, pp. 40–46, August, 2007.
