Abstract

The potential of ECAP sheet machine build in Monash University to refine the grain size, enhance mechanical properties, and improve deep drawability of the sheet was investigated for a representative aluminum alloy, AA5005. The annealed sheet was subjected to one, two, or four ECAP passes through 90º using route A or route C followed by annealing at 400 °C for 15 min. It was established that only one ECAP pass is required to obtain a significant improvement in both normal and planar anisotropy. A subsequent annealing enabled the recovery of ductility of the material lost during ECAP while maintaining the improved plastic anisotropy.
