Abstract

Advanced aero-propulsion engine designs now being considered for implementation require structural materials with high temperature strength and creep properties above 1300°C, in excess of the range where nickel base superalloys are now being used. A number of ordered single phase compounds having melting points above 1500°C have been identified which both hold promise for engine applications and are representative of a number of different crystal structures such as B2, C15 (Laves), A15, C1 and DO19. Elevated temperature characterization has been conducted on these compounds which includes ductile/brittle transition temperature determination, minimum creep rate analysis, elastic modulus, tensile strength and cyclic oxidation testing. The results of these tests have led to insight in the processing methods required for these compounds and selection of compounds based on elemental constituents and crystal structure.
