METHOD OF MANUFACTURING PARTS FROM ALUMINIUM ALLOYS Russian patent published in 1997 - IPC

Abstract RU 2087582 C1

FIELD: metal working. SUBSTANCE: method of manufacturing parts from aluminium wrought alloys containing at least one transition metal includes following operations: homogenation of ingot at 300-448 C, cooling to 18-35 C with the rate at least 100 C, heating to strengthening phase release temperature, subsequent preliminary plastic deformation at this temperature, at least one heating to ultimate plastic deformation temperature, and ultimate plastic deformation at this temperature with degree no more than 75% in one heating followed by heat treatment. Invention can be used in forging, rolling, and other shops at metallurgical works performing treatment of metals under pressure. EFFECT: enhanced efficiency of process. 1 tbl
