Abstract

A new technique on laser-shock flexible micro-forming (LSFF) of multilayer-metal composite sheets is investigated, and its feasibility is verified. It is found that there is no delamination or cracks in the formed parts under appropriate process parameters. The study results show that the forming depth of Ni/Cu/Ni metal composite sheets under LSFF is between the forming depth of copper foils and that of nickel foils, which increases with the increase of the laser energy and laser impact times. Surface roughening happens in the formed parts and the roughness increases with the increase of the laser energy.
