Abstract

In this study, the effect of cooling rate during homogenization treatment of AA 6063 aluminum alloy on the low-grade cold deformation-recrystallization properties has been investigated. For this purpose tapered tensile test specimens (one side 10 mm width and the other side 18 mm) were prepared from the material taken from billet produced by semi-continuous casting method. These specimens were homogenized at 560 degrees C for 6 h and cooled down at five different rates. Each group has three specimens. These specimens were then tensile tested to obtain deformation gradient and annealed at 450 degrees C, 500 degrees C, and 550 degrees C for 1 h. Following these treatments specimens were subjected to metallographic examination.
