Abstract

The texture evolution and mechanical anisotropy in an extruded AZ61 Mg alloy are examined. After warm extrusion, the alloy exhibits a refined grain structure and a strong basal texture. The tensile behaviors are examined in extruded specimens with the loading axis oriented at 0°, 45° and 90° to the extrusion direction. The 45° specimens exhibit lower yield stresses and higher ductility. The possible reasons for the mechanical anisotropy based on the Schmid factor calculations are analyzed.
