Claim Text:
1. An additive friction stir method for fabricating a rib joined to a metallic substrate through extrusion, comprising: providing a metallic substrate disposed with a surface of the substrate in communication with a die assembly comprising a forming cavity; translating a rotating non-consumable friction-stir tool along an opposing surface of the metallic substrate along a vector that overlies the forming cavity; and feeding the rotating non-consumable friction-stir tool with a consumable filler material such that interaction of the rotating non-consumable friction-stir tool with the substrate generates plastic deformation at an interface between the rotating non-consumable friction-stir tool and the metallic substrate such that the consumable filler and metallic substrate are extruded through the forming cavity to form a rib joined to the metallic substrate and consisting of the extruded material.
