Abstract
An experimental procedure has been developed
for the determination of FLCs at elevated temperatures. The
GOM ARGUS system was employed for measuring surface
strain based on pre-applied grids (pattern), and limit strains were
determined according to the ISO 12004-2:2008 standard.
Forming limit curves (FLCs) have been determined for AA5754
under warm forming conditions in an isothermal environment.
The tests were carried out at various temperatures up to 300oC
and forming speeds ranging from 5 – 300 mm s-1
. Results reveal
the significant effect of both temperature and forming speed on
FLCs of AA5754. Formability increases with increasing
temperature above 200oC. Formability also increases with
decreasing speed. The presented FLC results show that the best
formability exists at low forming speed and the high temperature
end of the warm forming range.
