Quenching is known as the most critical step in the sequence of heat-treating operations. The objective of quenching is to preserve the solid solution formed at the solution heat-treating temperature, by rapidly cooling to some lower temperature, usually near room temperature. The scope of this study is to construct the forming limit diagram experimentally for aluminum alloy (2024-T3) sheet, as received and after Quenching from solid solution temperature. The results which have been obtained experimentally showed that at (6 hours) after Quenching, there is a considerable effect on the FLC, Quenching increases the FLC at the as received condition in the range of (19-31 %) .
