Abstract
Abstract Constrained groove pressing (CGP) is a severe plastic deformation technique for sheet materials resulting in significant microstructural refinement and enhanced mechanical behaviour. CGP involves alternate pressing of sheets between corrugated and flattened dies under the plane strain deformation condition. The applicability of CGP for obtaining fine grained structures has been well documented for various metals and alloys. Processing and characterization of ultra-fine grain structures in aluminium(Al)and its alloys has been a subject of research over a period of time due to their application in wide range of industries such as automobiles aerospace, medical and so on. This study is aimed at reviewing the effect of CGP processing on the microstructural evolution and mechanical behaviour of pure aluminium and few commercially important Al alloy sheets reported in literature
