Abstract:

A modified composition NiAl 5 Ni was produced from which bodies were successfully fabricated by powder metallurgical techniques. Properly hot- pressed bars of the NiAl 5 Ni composition showed strengths in modulus of repture as high as 144,000 psi at room temperature and 68,000 psi at 980C. The air oxidation resistance of the modified NiAl 5 Ni composition was excellent up to 1095 C weight gains of the order of 1.25 mgsq cm were exhibited after 300 hr of exposure. Heat-shock properties were considered satisfactory on the basis of both NACA tests and performance in the Air Force heat-shock apparatus.
