Abstract: In a method for producing a high temperature alloy having increased creep strength, which comprises the steps of, forming a melt which consists essentially of 55-58 wt.% cobalt, 39-41 wt.% chromium, and 2.2-2.4 wt.% carbon; and solidifying said melt to obtain an alloy which is essentially a solid solution of chromium in cobalt as base alloy in which are embedded essentially parallel carbide filaments; the improvement is disclosed which comprises adding to said melt an amount of magnesium effective to deoxidize said alloy.

Abstract: In a cast anisotropic body comprising a monovariant ternary eutectic alloy of Co, Cr and C, which is segregated into a matrix, and a carbide dispersed phase, the matrix phase consisting essentially of a Co-Cr solid solution and the dispersed phase consisting essentially of a plurality of high strength carbide fibers oriented in substantial alignment and integrally embedded in the matrix phase, the improvement which comprises having contained in the matrix and/or dispersed phase, Ni in an amount of from 1.5 to 8.5 % by weight based on the total weight of the composition.
