Abstract: The influence of thermal pre-treatment on the formability of a precipitation-hardening
aluminium alloy AA-2024 has been studied for three different heat treatment conditions: annealed
(O-temper), solution treated and quenched (W-temper) and solution heat treated, quenched and then
cold worked (T-temper).The maximum draw angle has been determined and the geometrical
accuracy of specific SPIF formed parts has been compared. It is found that the maximum forming
angles of the blank formed in O-temper and W-temper conditions show a respective 41% and 32%
increase to those of the T-temper condition (initial blank).The hardness of the material
reduces significantly after annealing, while SPIF parts formed from W-temper blanks regain their
initial hardness after natural aging.
