DEVELOPMENT OF A NICKEL-BASE MATERIAL DISPERSION HARDENED BY ALUMINA FOR 1600 F TO 2000 F SERVICE

Abstract

The chemical, physical, and mechanical properties of a number of Ni-base dispersion-hardened alloys were studied. A technique involving partial oxidation of active Raney Ni catalyst was employed to attain a dispersion of Al2O3 in the matrix. The matrix compositions of the alloys were grouped into four classes: (1) Ni, (2) Ni solid solution, (3) Ni solid solution + Ni3(Al, Fe), (4) Ni3(Al, Fe). Data are presented for techniques of preparation, alloy composition, density, hardness, oxidation resistance, tensile strength, compressive strength, stress-rupture strength, and compressive creep strength.
