Ternary alloys containing combinations of Mo, Nb,Ta, Ti, and W produced alloys with tensile strengths of 60,000 to 80,000 psi at 1700 deg F. No oxidation- resistant complex alloys were found other than those containing significant amounts of Cr or Si. Ternary alloys of Co, Cr, and Mo had tensile strengths of 85,000 to 90,000 psi at 1700 deg F. These alloys were forgeable and oxidation resistant. Their main disadvantage was marginal ductility. Tantalum was found to alloy well with other strength-promoting elements, whereas titanium was generally unsatisfactory by lowering the melting point of the complex alloy if appreciable quantities were added.
