Descripción:
ECAE has been one of the most prolific techniques in the study of severe deformations of metallic alloys. Severe deformation on low melting temperature alloys has been scarcely studied due to the high dynamic recrystallization effects they usually present. In the current presentation we show ECAE deformation experiments performed in a 120o tool at room temperature in pure Pb and near eutectic composition Pb-62%Sn alloy. The samples were passed 5 times in a route A. Metallographic observation after each pass showed a completely recrystallized structure. Due to the high absorption presented by Pb for X-rays the textures were measured by neutron diffraction. Because of their high penetration and superior statistical capabilities the textures showed well defined patterns even in the cases when the strengths were rather weak.
