Abstract
Different manufacturing processes can be utilized to fabricate light-weight high-strength materials for their applications in a wide spectrum of industries such as aerospace, automotive and biomedical sectors among which accumulative roll bonding (ARB) is a promising severe plastic deformation (SPD) method capable of creating ultrafine grains (UFG) in the final microstructure. The present review discusses recent advancements in the ARB process starting with the ARB basics, intricacies of the underlying mechanisms and physics, different materials, surface and rolling parameters, and finally its key effects on different properties such as strength, ductility, fatigue, toughness, superplasticity, tribology and thermal characteristics. Moreover, results of recent computational investigations have also been briefed towards the end. It is believed that ARB processing is an emerging area with tremendous opportunities in the industrial sector and ample potential in tailoring microstructures for high-performance materials.
Highlights
Nowadays, bulk materials with high strength to weight ratio are in high demand in weight-critical industrial applications
ultra-fine grained (UFG) materials processed by accumulative roll bonding (ARB) may not be applied in industrial applications if they exhibit poor fracture response
Accumulative roll bonding is a severe plastic deformation process that involves rolling a stack of materials, sectioning into two halves, piling again and rolling repeatedly to produce an ultra-fine grain (UFG) structure
Summary
Bulk materials with high strength to weight ratio are in high demand in weight-critical industrial applications. Having an ability to bond similar and/or dissimilar materials, ARB is emerging as a cost-effective SPD technique to obtain large UFG sheets or multi-layered composites structures by accumulating large strains usually by repeating the procedure. It can be scaled up industrially as a continuous operation. Process where fabricate composite filler metals of tungsten inert gas welding where the results revealed that the or more sheets are stacked together and passed through the rolls to apply plastic deformation; the yield strength of welds was significantly when employing. Commonly used as acid containers with a low-thickness stainless steel (for inner side) stacked to a thick low-carbon metal (for outer side)
