The powder mixture can be hot-worked in the solid-phase temperature range, liquid phase temperature range or solid-liquid phase mixture temperature range of the Al alloy. A dispersion strengthening powder can be further admixed with the mixture of Al alloy powder and Ni powder.Field of SearchTreating loose metal powder, particle or flakeTreating consolidated metal powder, per se (i.e., no sintering or compacting step present) Aluminum base Iron, cobalt, or nickel containing Consolidation of powders Extrusion Isostatic/Hydrostatic pressing Rolling With nonmetal constituent - Silicon(Si) considered a metal (e.g., cermet, etc.) Oxide containing Oxide of Aluminum(Al), Beryllium(Be), Magnesium(Mg), Alkaline earth metal, Scandium(Sc), Yttrium(Y), Lanthanide metal, Actinide metal, Titanium (Ti), Zirconium(Zr), or Hafnium(Hf) Carbide containing Base metal one or more of Beryllium(Be), Magnesium(Mg), or Aluminum(Al) Mixture contains particles of nonmetal Oxide containing (e.g., dispersion strengthened, etc.) Laterally noncoextensive components (e.g., embedded, etc.) | |
