Over the last 30 years, research has shown that nanostructured materials, especially Ferritic ODS alloys, have superior performance in the harsh environments required by high temperature, energy conversion processes. However, due to the powder processing methods used to manufacture ODS alloys, their costs have been prohibitively high. For these alloys the barrier to their implementation is a lack of scalable, high-volume manufacturing methods. To realize the advantages available from nanostructured metals, new manufacturing processes need to be developed that can produce useable product forms (rod, tube, plate or sheet) that retain the nano- or high performance microstructures in the bulk materials. Recent research at PNNL and the University of South Carolina, has demonstrated a new Shear-Assisted Extrusion method that can fabricate bulk materials from nanostructured precursors (billet or powder). This presentation will outline the method and performance of extrusions made by the process, and its application to Ferritic ODS alloys.
