The Principle of the Explosive Welding for Multilayer Amorphous Foils

A dynamic model about the explosive welding of multilayer foils was given in this paper. We proved that the particle velocity behind the shock wave was the impact velocity between the two foils and the dynamic behavior of the multilayer foils system was similar to that of the porous material system. Otherwise, a heat-conduction model was used to explain the heat conduction in the explosive welding of multilayer amorphous ribbons. With above theories a welding window of Fe78B13Si9 amorphous alloy was also given which is in good agreement with its explosive welding results.
