Abstract:A Pb-0.08Ca-2Sn alloy was subjected to rolling at room temperature to different final thicknesses. Annealing treatments at temperature ranging from 80 to 120 °C led to recrystallization of the samples as shown by resistivity and micro-hardness measurements. The deformation texture determined through X-ray diffraction is qualitatively the Brass type. The measured Lankford anisotropy parameter R and its evolution are close to the determined one using a self consistent approach. The R value evolution with angle to rolling direction shows the presence of planar anisotropy and poor drawability. The recrystallization in annealing at 80−120 °C is achieved within time period up to 3×104 s. The recrystallization texture is a retained deformation texture with an emerging Cube component.
