Abnormal extrusion texture and reversed yield asymmetry in a Mg–Y-Sm-Zn-Zr alloy


An extruded Mg–Y-Sm-Zn-Zr alloy exhibited an abnormal texture component, that is, the c-axis of most grains was aligned parallel to the extrusion direction. The reversed yield asymmetry with a tension/compression of 0.94 was attributed to the activation of extension twinning under tensile strain.
