Abstract Scope |
The automotive industry face demands to produce lightweight vehicles and substituting steel with aluminium is a straightforward solution. Age hardenable aluminium alloys are attractive candidates when the aim is a combination of high strength and good ductility. To obtain a solution that is suitable for high-volume production, an integrated hot forming and in-die quenching process has been developed. However, this method changes the temperature exposure of the part and alters the precipitation and clustering sequence during hardening.
In the present work, the effect of the modified temperature sequence has been investigated. The method has been experimentally simulated by application of a water-cooled compression tool combined with subsequent age-hardening. The temperature experienced by the blank has been measured throughout the process, and the effect of variations in the quench-interruption temperature has been investigated. The results indicate that there is little difference in strength and hardness by changing the closed-die time. |
