The results show that: the plate organization is mainly composed of α -Mg matrix, β -Mg17Al12 phase and α + β divorced eutectic, showing dendritic morphology; In surface and edge of the plate, β -Mg17Al12 phase is mainly distributed at the grain boundary and the density is bigger, formed net-shape; In center and central of the plate, spherical β -Mg17Al12 phase is dispersed in α-Mg matrix, formed lamellar-shape; The main reason for the edge crack in the cast-rolling process is in the slab edge interdendritic low-melting eutectic phase and β -Mg17Al12 phase of grain boundary which are easy to be crack source, and extend outward along the crystal; The tensile specimen showes brittle cleavage fracture characteristics, and its mechanical property is obvious anisotropy.
