Abstract
In this study, the effect of homogenization heat treatment on precipitation and recrystallization kinetics as well as geometry of recrystallized grains during subsequent annealing of direct chill cast hot rolled and twin-roll cast AA 3105 strips was investigated. For this purpose, homogenization heat treatment was conducted on AA 3105 strips after cold rolling with an equivalent strain of 0.66. Homogenized and non-homogenized strips were then cold rolled with an equivalent strain of 1.06. Results reveal that homogenized twin-roll cast AA 3105 strip exhibits lower recrystallization temperature as compared to that of non-homogenized one and finer as well as quasi-equiaxed grains through particle-stimulated nucleation mechanism after soft annealing. On the other hand, for direct chill cast hot rolled AA 3105 strip, homogenization heat treatment leads to lower recrystallization kinetics.
