The Mg/Al laminated composites were prepared by the accumulative roll bonding (ARB) at ambient temperature using the commercial pure magnesium and pure Al sheets as starting materials. Microstructure of both Mg and Al layer were refined during ARB processing. Neutron diffraction was employed to investigate the texture evolution of this kind of laminated composite. Both the Mg and Al layer of the primary sandwich exhibited dominant shear texture. During the following accumulative roll bonding, the texture of Mg layer transformed to typical rolling texture while the Al layer showed a combined texture type including evident β fiber and the Rotate Cube component
