Abstract

In
this study, the effects of annealing parameters on the formability and
mechanical properties of Al2024-T3 sheet material were investigated
experimentally. Annealing process were applied at 100 °C, 200 °C, 300 °C, 400
°C annealing temperatures and at 6 minutes, 30 minutes, 60 minutes annealing
times. The forming operations were applied in 10 mm / sec deformation velocity
and in V bending dies with an angle of 30 °, 60 °, 90 °, 120 °. In the
experimental studies, it was determined that there was no significant change in
the hardness values of the specimens at temperatures less than 300 ° C
annealing temperature and 6 minutes annealing time parameters, but an irregular
changes were observed in the mechanical properties of specimens. However, it
was observed that there were a significant decrease in the hardness values and
mechanical properties of the test specimens after the annealing temperature of
300 ° C and the annealing time of 6 minutes. It has been observed that the
samples only has been formed successfully in a 30 ° die angle and at low
temperatures (RT - 100 ° C - 200 ° C). It has been observed that a successful
forming process has been performed in 30 ° and 60 ° die angles by increasing
the annealing parameters values (400 ° C - 30 min or 400 ° C - 60 min).
However, forming defects such as cracks and fractures were encountered in
forming processes using 90 ° and 120 ° die angled.
