Abstract:As a new severe plastic deformation method, groove pressing shows significant advantages of fabricating bulk ultra-fine grained sheet metals and has broad prospects for industrial applications. Firstly, the fundamental principles, plastic mechanics analysis and classification of groove pressing are introduced. Then, the influence rules and mechanism of process factors such as pass number, deformation temperature and die structure on groove pressing are reviewed. Several key problems such as thermal stability of processed materials, process improvements and deformation path, deformation homogeneity analysis and process optimization are summarized. Finally, the development trend in future of research on groove pressing is prospected.
