Abstract

Surface friction welding (SFW) is a newly developed technology fur joining thin metal sheets, which utilizes friction between tool and weldment. In the present study, the 5052 and 1050 Al sheets were locally surface-modified using SFW technology. Formability of the locally surface-modified sheets was superior to that of the parent material. Yield or tensile strengths of the locally surface-modified specimens were lower then those of the parent material, but elongations of the locally surface-modified specimens were higher then that of the parent material.
