Bonding by plastic deformation is a key technology to manufacture lightweight components with high perform-ance. The characteristic and application of main bonding methods were introduced, including roll bonding, extrusion bond-ing, diffusion bonding, press bonding and friction welding. The research progress on the microstructure evolution, mechani-cal property and defects characterization of bonds by plastic deformation was summarized. The formation mechanisms of metallurgical bonds by plastic deformation were summarized. On this basis, the outlook of the further research and develop-ment on this technology was given.
