A process for forming extruded products using a device having a scroll face configured to apply a rotational shearing force and an axial extrusion force to the same preselected location on material wherein a combination of the rotational shearing force and the axial extrusion force upon the same location cause a portion of the material to plasticize, flow and recombine in desired configurations. This process provides for a significant number of advantages and industrial applications, including but not limited to extruding tubes used for vehicle components with 50 to 100 percent greater ductility and energy absorption over conventional extrusion technologies, while dramatically reducing manufacturing costs.

In a method for producing a mixture of a metallic matrix material and an additive, a metallic bulk material is molten in a multi-shaft screw machine in a heating zone thereof by means of an inductive heating device to form a metal matrix material. As the at least one housing portion of the housing of the multi-shaft screw machine is made of a non-magnetic and electrically non-conductive material at least partly in the heating zone, a high and efficient energy input for melting the metallic bulk material is achievable in a simple manner. The additive for producing the mixture is admixed to the metallic matrix material by means of treatment element shafts of the multi-shaft screw machine.
