Abstract:Large plastic deformation is the main forming technology for preparing ultrafine-grained materials. Among the severe plastic deformation technologies, the accumulative roll bonding (ARB) process is simple, with low requirements for dies and low cost, which can continuously produce large-size fine-grained plates and has been widely used. The research status of cumulative rolling process at home and abroad was reviewed from the aspects of microstructure, mechanical properties, strengthening mechanism and interface bonding mechanism of cumulative rolling material. It is very important to improve the plasticity of ARB materials. The preparation of ARB composites with high strength and high ductility will become a hot topic in the future.
