Electromagnetic extrusion
A system and method for an improved material flow through an extrusion machine by altering the material properties in a magnetic field are provided. The electromagnetic extrusion system includes a ram that is moved into a chamber containing an extrusion material to force the extrusion material out of an opening defined, at least in part, by a die to create an extrusion with a cross-sectional shape corresponding to the predetermined shape of the opening. An electromagnetic winding of electrically conductive material is embedded within a tool retainer block surrounding the container and is helically wound about the chamber and carries a DC electrical current to generate a magnetic field having a magnetic flux density of at least 2 Tesla within the extrusion material to dissipate dislocation defect structures in the extrusion material being extruded via the magnetoplasticity effect. The magnetic field therefore provides for reduced flow stress on the tooling.

Insert casting or tack welding of machinable metal in bulk amorphous alloy part and post machining the machinable metal insert
Provided in one embodiment is a method of forming a connection mechanism in or on a bulk-solidifying amorphous alloy by casting in or on, or forming with the bulk-solidifying amorphous alloy, a machinable metal. The connection mechanism can be formed by machining the machinable metal.
Method for Forming Hollow Profile Non-Circular Extrusions Using Shear Assisted Processing and Extrusion (ShAPE)
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.
Extrusion press and method of using
An extrusion press including a ram having a ram body configured for movement along a ram axis, and a compaction container defining a compaction compartment and having a compaction container axis. The compaction container is rotatable between a first orientation wherein the compaction container axis is not aligned with the ram axis and a second orientation wherein the compaction container axis is aligned with the ram axis such that the ram body is movable into the compaction compartment.
