Abstract
Disclosed is a process for forming a new group of cobalt-based alloys containing 3-18% hafnium carbide (HfC), the HfC having a particle size finer than about three microns. The class of alloys exhibits excellent tensile strength characteristics at very low temperatures, exhibits very good time-temperature stability, and shows excellent oxidation characteristics even at temperatures above about 1000.degree. C. In addition, the alloy is attractive for use in the wrought state because of its ductility and low-temperature toughness characteristics.
