FIELD: metallurgy; electrical engineering.
SUBSTANCE: invention relates to metallurgy and electrical engineering and can be used in the production of high-strength electric wires to be used in wire products operating under conditions of high mechanical and thermal loads. Wire includes longitudinally arranged high-strength element in the outer casing from copper or a copper-based alloy, which comprises a copper matrix and ribbon cross-section fibers evenly distributed over the section and elongated along the wire longitudinal axis. Fibers are made of niobium or a niobium-based alloy. Material for a high-strength element of niobium or a niobium-based alloy is obtained by vacuum arc melting with a consumable electrode; composite billet is formed by placing the obtained ingot in a cylindrical pipe made from copper or a copper-based alloy; composite billet is deformed by pressing with a stretching of more than 2, pressed bar is deformed by drawing to the final diameter.
EFFECT: technical result is the creation of nanocomposite wires with preset combination of strength-conductivity properties.
