Shear assisted processing and extrusion (ShAPE) is a solid-phase technique that can be used to extrude wire, rod, tube or non-circular cross sections directly from powder, flake, chips or solid billets. Unique aspects of ShAPE are the ability to refine microstructure into the UFG range, control textural alignment, promote solute segregation to grain boundaries and uniformly distribute second-phase particles within the metal matrix. By exploiting one, or a combination of these phenomena, advancements in bulk material properties such as creep strength, corrosion resistance, electrical conductivity, ductility and energy absorption are possible. An overview of the ShAPE process will be presented with examples drawn from current research in lightweight structural metals, oxide dispersion strengthened steels and semi-conducting thermoelectrics.
