Библиографическое описание: ELECTRICAL WIRE PRODUCTION FROM Al - Ce - La ALLOY RODS AFTER ELECTROMAGNETIC MOLD AND COMBINED ROLLING ‑ EXTRUSION : научное издание / D. Voroshilov, S. Sidelnikov, D. Darmazhapov [и др.]. - Текст : непосредственный // Journal of Chemical Technology and Metallurgy. - 2025. - Т. 60, № 2. - С. 327-336. - ISSN 1314-7471. - ISSN 1314-7978, DOI 10.59957/jctm.v60.i2.2025.15.
Аннотация: <jats:p>The paper presents the results of the power parameters when producing rods and wires with Ø 2 mm from them and the mechanical and electrical properties of the resulting semi - finished products from an alloy of the Al - Ce - La system with a rare earth metal content of 1 %. The wire is produced using the method of combined rolling-extrusion (CRE) from the billet Ø 12 mm after electromagnetic mold (EMM), and further drawing. The results of experimental studies of the process of producing longish deformed semi-finished products from the Al - 1 % REM alloy using the CRE-200 combined processing unit are presented. Data were obtained on the mechanical properties of hot - extruded rods Ø 5 mm and Ø 9 mm, as well as wire Ø 2 mm obtained from these rods after implementing the combined processes of rolling - extrusion. It was found that the proposed processing modes make it possible to obtain rods with Ø 9 mm and Ø 5 mm using a combined rolling - extrusion method from workpieces after EMM with diameter 12 mm. The forces on the rolls and die were measured during the implementation of the investigated combined processes. The plasticity of the resulting rods Ø 5 and 9 mm after the CRE method was quite high (elongation to failure reached 14 - 26 %). When drawing wire up to Ø 2 mm, no intermediate annealing was required. The values of electrical resistance do not exceed 0.0271 Ω mm2 m-1 for rods and from 0.0301 Ω mm2 m-1 for wire with a diameter of 2 mm, depending on the processing modes. At all stages of the experimental studies, the structure of the metal was studied and the patterns of change in physical and mechanical properties depending on the processing modes were established.</jats:p>
