Abstract
Magnesium/aluminum laminated composites were fabricated by diffusion bonding method, and interfacial characteristics were measured by nano-indentation to know how to improve the interfacial properties of heat treated composites. The results reveal that laminated composites with desirable bonding can be prepared by the diffusion bonding with three sets of processing parameters, including 400°C/30 MPa/10 min, 400°C/40 MPa/10 min, 400°C/30 MPa/20 min, however, the diffusion layer is not visible in the conditions of 400°C/30 MPa/10 min. Diffusion layer thickness of the composites can be remarkably increased with heat treatment, and nano-hardness of diffusion zone is 3 times higher than that of the matrix, and the Young's modulus is located in the range of that of magnesium alloy and aluminum alloy.
