  • Eutectic superalloy compositions and articles
    Patent number: 4543235
    Abstract: An improved eutectic superalloy composition is described. The eutectic composition upon solidification forms a gamma matrix, containing a substantial quantity of particles of the gamma prime phase, and containing about 12% by volume of aligned continuous chromium carbide fibers (Cr.sub.3 C.sub.2). Material of this composition is provided with significantly improved mechanical properties and surface stability through the addition of approximately one atomic percent of the material selected from the group consisting of manganese, technetium and rhenium. Directionally solidified articles of this composition have utility as gas turbine engine components.
