Abstract

The high-temperature strength and ductility of cobalt — refractory-metal alloys designed for advanced turboelectric space-power systems were investigated. An average life of over 200 hr was obtained at 1800°F and 15,000 psi with the strongest alloy, Co-25W-1Ti-1Zr-0.4C. Workability of the stronger alloys was demonstrated by rolling.
