| Abstract |
Nickel aluminides are a family of materials which offer the potential of improved high temperature performance over conventional nickel based superalloys. The synthesized material has been characterized by x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and selected area image analysis. The mechanical properties of the Ni₃Al/NiAl alloy have been determined as a function of temperature through compressive and four point flexural tests. The lamellar aluminide provides synergistic properties of each of the monolithic aluminides resulting in appreciable room temperature tensile ductility, reasonable room and elevated temperature fracture toughness and higher compressive yield strength than those of obtained in monolithic NiAl. |
