Abstract
The forming process of drawing texture and the recrystallization behavior of (α+β) brass rod have been investigated by means of determination of the ODF and transmission electron microscopy.The preferred fiber component is composed of the 〈111〉+〈100〉 duplex fiber texture which is less in intensity than that of α mono-phase brass rod because of the presence of β-phase. The fiber component in β-phase is composed of the 〈110〉 fiber texture which is a stable orientation in bcc metals. The volume fraction of β-phase increases with the increase of the drawing ratio and reaches about 40% by drawing to 90% reduction, because the distorted β′-phase and fct α1-phase are developed during deformation.Regarding the recrystallization behavior, the 〈111〉 fiber texture remains in α-phase, and the 〈110〉 fiber texture remains in β-phase with the continuous recrystallization.Microscopic examination shows that the α-phase bulges into the β-phase on annealing.
