Abstract

A magnesium alloy containing the Mg–Al–Gd long-period stacking-ordered (LPSO) platelet precipitates parallel to the basal plane was found to deform by c -axis tension twinning on {11[¯2]1}, whose passage causes the bending of the LPSO platelets, when Mg grains are oriented favorably for extension along the c -axis during plane-strain compression at room temperature. The bending of the LPSO platelets was found to be caused by the deformation twinning equivalent to {11[¯2]1} twinning in the Mg matrix.
