Investigation structure and properties of wire from the alloy of AL-REM system obtained with the application of casting in the electromagnetic mold, combined rolling-extruding, and drawing

The paper presents the results of studies structure and properties a wire with diameter 0.5 mm from an alloy Al-REM system rare-earth metal content 7–9%. Wire obtained as result implementation technology its manufacture using methods casting into electromagnetic mold (EMM), continuous extruding, drawing. rheological continuously cast round billets experimental are determined. modeling analytical assessment possibility carrying out process combined rolling-extruding (CRE) such in closed box-type roll groove extruding unit carried out. features shaping have been studied. temperature-speed technological parameters were found at which CRE can be stable mode operation. Data for forces acting on die rolls during rolling-extruding. obtaining longish deformed semi-finished products laboratory CRE-200 pilot plant CRE-400 presented. has studied; data ultimate tensile strength, yield relative elongation, electrical resistance hot-extruded rods wires cold-worked annealed states obtained. It was that proposed processing modes make it possible to obtain by method 9 industrial conditions 18 mm, means EMM. cold-deformed state drawing containing 7–9% metals required physical mechanical properties.
