- Abstract
Due to the low density and high tensile strength, the aluminium alloy EN AW-7075 offers a high lightweight potential for structural components. In recent years, 7xxx-aluminium alloys have been the subject of numerous investigations in the field of warm and hot forming and suitable heat treatments to fully use their potential for applications in automotive bodies. Alternatively, forming blanks of these alloys at room temperature in the W-temper state is favourable 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 this investigation 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 after solution heat treatment and then artificially aged. To determine the influence of the quenching rate, hardness tests were carried out.
