METAL matrix composites have attracted attention in various fields such as automotive, aerospace and other advanced applications.[1,2] Many aluminum matrix composites (AMCs) with the addition of whiskers or particles have been extensively studied due to the high stiffness, low density and excellent wear resistance.[3–5] However, although the tensile strength and elastic modulus of AMCs are enhanced due to the introduction of reinforcements, the AMCs cannot meet the requirement of many

METALLURGICAL AND MATERIALS TRANSACTIONS A
structural materials due to the reduced ductility and instantaneous failure compared with traditional monolithic materials. Therefore, the strength and ductility of AMCs should be combined and tailored to improve the processability and formability of structural materials. A typical example of a structural component is the use of graphite fiber/Al composite as a high-gain antenna boom in the Hubble space telescope.[6] It is attractive to develop sandwich composites consisting of metals and AMCs with various properties to increase the comprehensive mechanical properties of AMCs. Rolling and extruding were considered feasible techniques for obtaining the metal/AMCs laminated composites with good interfacial integrity. These processes have been used to produce high-performance metal/AMCs sandwich composites, such as Al89Ni3Gd7Fe1/Al,[7] 6061-SiCp/1050[8] and 2014-SiC/2014,[9] etc. Hassan and Lewandowski[7] extruded Al89Ni3Gd7Fe1 powders inside an aluminum tube at 673 K to fabricate Al89Ni3Gd7Fe1/Al-laminated nanostructure composites. They found that the bend ductility and notched toughness were significantly improved because of the addition of the ductile Al layer. Zhu et al.[9] investigated the mechanical properties of roll-bonded 2014-SiC/2014 sandwich composites and showed that the tensile strength and interfacial bonding strength of sandwich composites improved due to the addition of SiC
nanoparticles. Science the mechanical properties of sandwich composites are generally considered to be controlled by their microstructure and texture, it is important to study the microstructure and texture
