摘要：

The paper presents an experimental research regarding the formability of an aluminium alloy used in the automotive industry. The experiments were performed at the Institute of Metal Forming Technology (Stuttgart University, Germany) on a AA7021-T79 aluminium alloy sheet. The Nakajima test is the widely used method to determine the Forming Limit Diagram by conducting experiments for different geometries of the specimens. The "Shock Heat Treatment Method" was applied in order to improve the formability of the aluminium alloy. The method consists in performing the heat treatment that includes heating, quenching and precipitation hardening (aging) to increase the strength properties of the alloy. In the case of the AA7021-T79 alloy, the first step was to bring the material to the T4 state, and then to apply the SHT at 350 degrees C. The paper presents the forming limit diagrams obtained after performing the heat treatment mentioned above.
