| Abstract Scope |
In recent years, 7xxx-aluminum alloys have been the subject of numerous investigations in the field of warm and hot forming and suited heat treatments to fully utilize its potential for applications in automotive bodies. Alternatively, forming blanks of these alloys at room temperature in the W temper state is favorable since conventional tools can be used. However, this condition is unstable. As the ageing duration after quenching increases, the formability decreases due to natural ageing. Hence, the objective of the investigations was to determine the formability of EN AW-7075 as a function of the ageing time. Furthermore, since the quenching rate after solution heat treatment influences the resulting mechanical properties, an adapted process route to manufacture components with tailored properties was explored. For this purpose, samples were partially quenched and then artificially aged. To determine the influence of the quenching rate, hardness tests and microstructure analysis were carried out. |
