Manufacturing technology of aluminium wire from alloy 01417 with adjusted level of mechanical properties

In the 70s of the last century, Soviet scientists developed an aluminum alloy with 7% rare earth elements (REE), which at melt cooling speeds of up to 104 deg/s are dispersed into intermetallic phases, which significantly increase the heat resistance, corrosion resistance, and weldability of finished products for conductive material. To ensure melt cooling rates of up to 104 deg/s in those years, centrifugation of granules in water was used. To increase the efficiency of this redistribution, a pilot industrial line was used for continuous pellet pressing by the Conform method. A method has been developed for producing small-section billets (Æ 8-12 mm) with a crushed structure from Al-REM system alloys by continuous casting in electromagnetic crystallizer (EMC) mounted at Magnetic Hydrodynamics Scientific and Production Center LLC. In this method of casting, a dispersed structure is obtained with a slight intra-dendritic segregation, which guarantees a high level of mechanical properties...
