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