| Abstract Scope |
It is well known that the strengthening of 6000 series aluminum can be achieved via billet heating, direct extrusion and subsequent water or air quenching. The metallurgical characteristics of the Al-Mg-Si alloy system renders it relatively quench insensitive thus allowing billet preheats and the heat of extrusion to substitute for a separate, more expensive solution heat treat step. However, the linkage of direct extrusion to the quench comes with a risk of quench interruptions that, under certain conditions, can reduce the localized strength of the extrusion. These localized areas reduce the consistency in performance and therefore it is desirable to minimize the strength variation that result from these events. The work presented in this paper is intended to better understand two key inputs to these quench interruptions (quench delay time and alloy chemistry) with the goal of making the process more robust and therefore less sensitive to quench delays. |
