Development of aluminum matrix composites through accumulative roll bonding: a review

Accumulative roll bonding (ARB) is a severe plastic deformation technique commonly applied to produce ultrafine grain materials. ARB has evolved as a promising method in the last decade to produce aluminum matrix composites (AMCs) effectively, overcoming the common issues faced in various casting methods. This review summarizes the research works accomplished in producing AMCs using ARB and critically discusses the literature on each aspect. Homogenous distribution of reinforcement particles in the composite is exceptionally achieved in this process. The factors affecting the distribution, the breakage of particles and the grain size are critically reviewed and elucidated. The interfacial details and porosity issues are addressed. The difficulty in processing nano- and multiple particles to produce AMCs is explained. ARB provides high-strength composites. The underlying strengthening mechanisms for significant improvement in tensile, wear and corrosion properties are explained. ARB is recently applied as a secondary processing tool to improve the distribution and properties of cast AMCs. This aspect of ARB is further covered. The review concludes with applications, future development of this process and extensions to produce other metallic composites. Graphical Abstract: (Figure presented.)
