ABSTRACT:
A single crystal nickel-base super alloy is disclosed having good high temperature strength with improved metallurgical stability and environmental resistance. The single crystal alloy of this invention is characterized by the addition of rhenium for high temperature strength, the inclusion of cobalt to increase metallurgical stability by inhibiting the formation of sigma phase, and the ellimination of vanadium to enhance hot corrosion resistance. The nominal composition of my new single crystal alloy is 8-10% Co, 5% Cr, 2% Mo, 5% W, 3% Re, 5.5% Al, 1.5% Ti, 6.3% Ta, and the balance Nickel.
