Abstract: The method of producing composite material with a high complex of mechanical properties, consisting of vanadium alloy inner layer V—3-11 wt % Ti—3-6 wt % Cr and two outer layers of stainless steel of ferritic grade with chromium content of not less than 13 wt %, includes preparation of a composite workpiece consisting of said inner layer and outer layers, hot treatment by pressure and subsequent exposure in furnace. Prepared composite workpiece, thickness of inner layer of which is 1.5-2 times more than total thickness of outer layers of stainless steel, hot working is performed with pressure of the workpiece in the temperature range of 1,050-1,150° C. with degree of reduction from 30 to 40% and with subsequent exposure for 1-3 hours with temperature reduction to 500-700° C., then annealing workpiece by heating to temperature of 850-950° C., holding for 2-4 hours and subsequent cooling in furnace.

Abstract: This invention relates to metallurgy, more specifically, to wrought aluminum base alloys, and can be used for the fabrication of products with up to 350° C. working temperature range. The technical result achieved in the first and second objects of this invention is providing a new heat resistant aluminum base alloy the wrought semifinished products of which (sheets, rods, wire, die forgings products or pipes) have high strength, heat resistance and electrical conductivity. Said technical result is achieved in the first object of this invention as follows. The aluminum base alloy contains copper, manganese, zirconium, silicon, iron and chromium in the following amounts, wt. %: Copper 0.6-1.5 Manganese 1.2-1.8 Zirconium 0.2-0.6 Silicon 0.05-0.25 Iron 0.1-0.4 Chromium 0.01-0.

Abstract: A substrate for depositing diamond by CVD, comprising a base body of hard material and a coating layer that holds diamond particles as seed crystal in a matrix and is deposited joined thereto on a surface of said base body, wherein: the seed diamond particles have an average particle size of 1 ?m or smaller; the matrix comprises a first metal selected from a first group of Si, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W and/or a first compound between said first metal and a non-metallic substance selected from boron, carbon and nitrogen, said matrix holding the diamond particles distributed therein; and a joint zone developed as a result of a diffusion process and extending over said base body and coating layer comprises either or both atoms of said first metal and a component metal of the hard material.
