摘      要：Over the last five years, accumulative roll bonding （ARB） has been used to produce aluminum-based metal matrix composites （AMMCs） with ultrafine-grained （UFG） structure. Al/Al2O3 [1-3], Al/SiC [4], Al/B4C [5,6], and Al/WC [7] are currently fabricated using ARB because of the resulting highly uniform reinforced particle distribution. ARB composites have higher strength but poorer ductility than unreinforced UFG matrix because stress is concentrated in the reinforced phase-Al matrix interface during tensile process. In the present study, we introduced Al-Zn regions to AI matrix by ARB to obtain AMMCs with high strength and ductility. The dissolution and precipitation of Zn atoms in Al matrix, as well as the effects of Zn on the ductility of AMMCs, were also analyzed.
