PHASE STABLE CARBIDE REINFORCED NICKEL-BASE SUPERALLOY EUTECTICS HAVING IMPROVED HIGH TEMPERATURE STRESS-RUPTURE STRENGTH AND IMPROVED RESISTANCE TO SURFACE CARBIDE FORMATION Monocarbide reinforced nickel-base eutectic superalloys which are substantially phase stable and have improved high temperature stress-rupture strength with improved resistance to the formation of surface nucleated carbides are provided. These superalloys are especially suited for making unidirectionally solidified anisotropic metallic bodies in the form of vanes and rotating blades for aircraft gas turbine engines.
