METHOD FOR PRODUCING A CONDUCTOR FROM AN ALLOY OF THE AL-FE SYSTEM Russian patent published in 2024 - IPC B22D21/04 C22F1/04 H01B1/02 

FIELD: non-ferrous metallurgy and electrical engineering.

SUBSTANCE: methods for producing high-strength alloys of the Al-Fe system used for the production of conductors in the form of wires, plates and busbars intended for use in electrical products operating under high mechanical loads with the maximum permissible continuous operating temperature 150°C. The method includes obtaining a molten iron in aluminium, casting and cold deformation of the cast billet, while obtaining a molten iron in aluminium is carried out at a temperature of 850-900°C, exceeding the liquidus temperature for these alloys, the production of a cast billet in the form of a rod with a diameter of 8 to 16 mm is carried out by continuous casting in an electromagnetic crystallizer with a cooling rate of 1000-3000° C/s, ensuring the formation and uniform distribution in the aluminium matrix of highly dispersed intermetallic particles of the iron-aluminium phase, the average size of which does not exceed 180 nm, in at least one direction, and the subsequent cold deformation of the rod is performed by drawing.

EFFECT: increase in mechanical strength while maintaining high values of electrical conductivity and heat resistance at temperatures of long-term operation in the temperature range up to 150°C.
