THERMOMECHANICAL PROCESSING OF LITHIUM-CONTAINING ALUMINIUM ALLOY PARTS

摘要

FIELD: thermomechanical treatment of parts. SUBSTANCE: method involves hardening, ageing at 20 to 125 C, tensile deformation, and final ageing; first and final ageing are conducted at temperature 55 to 120 C higher than solubility temperatures of Guignier-Preston regions. EFFECT: improved quality of parts due to their better plasticity while their high strength is retained. 1 tbl
