METHOD FOR THERMOMECHANICAL TREATMENT OF SEMIFINISHED PRODUCTS OF ALUMINIUM ALLOYS

摘要

FIELD: non-ferrous metallurgy, possibly production of calibrated rods. SUBSTANCE: method for thermomechanical treatment of semifinished products of aluminium alloys containing manganese comprises steps of hot deformation and quenching realized at one heating process at rate (10- 15)C/min; preliminary aging at (5-30)C for 0.5-16 hours; plastic deformation with degree (5-19)% and final aging. EFFECT: enhanced limit strength, increased percentage elongation of semifinished products. 2 tbl, 2 ex
