摘要: The present invention provides a continuous powder extrusion method for making an article having a profile including an outer shape and optionally including one or more inner hollows. One or more bulk material powders and one or more binders are provided, and the bulk material powders and the binders are mixed to form a mixture. A die is provided, the die optionally including a mandrel having one or more shapes. The mixture is extruded through the die and the optional mandrel to produce a green form. The green form is debound to produce a brown form and the brown form is sintered to produce a densified form. The densified form is optionally processed using thermal, mechanical, and/or thermomechanical processing to produce a wrought form. The densified or wrought form is optionally cut to a length and/or finished using traditional metal finishing processes.

摘要: A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.

摘要: Material processing systems are disclosed. Some systems include methods of eliminating or reducing defects in elongate workpieces that can undergo large deformations during processing. Some systems include apparatus configured to facilitate such large deformations while maintaining internal stresses (e.g., tensile stresses) below a threshold stress. Some disclosed systems pertain to powder extrusion techniques. Continuous and batch processing systems are disclosed.
