Popis: LZ91 magnesium alloy extruded sheets were subjected to cold rolling. The microstructure and texture evolution were tracked using optical microscopy (OM) and X-ray diffraction (XRD). The α-Mg and β-Li phases were elongated along rolling direction (RD), contributing to the formation of a thin lamellar “sandwich” structure. This “sandwich” structure is favored for glissile dislocation of α-Mg phase during rolling. The α-Mg and β-Li phases are near Burgers orientation relationship, resulting in an unusual RD texture component in (0002) pole figure. Keywords: LZ91, Microstructure, Texture, Burgers orientation relationship
