Abstract Scope Accumulative roll bonding (ARB) is a novel severe plastic deformation (SPD) technique used to produce ultrafine-grained material through repeated stacking and roll bonding. This technique is advantageous over other SPD methods in that bulk samples can be produced for subsequent microstructural and mechanical property characterization. With the bulk production of submicron-sized grains in aluminum alloys, low temperature superplasticity has been proven possible in Al 5083 alloys. One of the major difficulties associated with ARB is the occurrence of edge cracking. Edge cracking can reduce the process yield, making it difficult to produce bulk samples. This work explores the root cause of edge cracking during accumulative roll bonding and identifies methods to prevent its occurrence.
