Abstract (en)
The invention relates to a method of manufacturing an areal component made of one piece from an areal semi-finished part of an age-hardenable aluminium alloy, the method comprising an age-hardening treatment wherein the alloy is, subsequent to a solution heat treatment of the semi-finished part, cooled down in a quenching process to a first temperature allowing cold-working and a natural and/or artificial aging of the age-hardening treatment is performed after optional cold-working steps, wherein a warm sheet-forming process of the semi-finished part is inserted amid the quenching process, splitting the quenching process in at least two quenching regions, one above a second temperature at which the warm sheet-forming process begins and another one above the first temperature, the second temperature being not higher than the maximum of 320°C and 85% of the recrystallization temperature of the alloy and not lower than the minimum of 120°C and 30% of the recrystallization temperature.
