Abstract
This disclosure relates to a eutectic alloy, and article made from the alloy, in the nickel-aluminum-molybdenum system which may be directionally solidified to produce a microstructure consisting of a ductile matrix phase of gamma prime or gamma prime/gamma containing a reinforcing fibrous or lamellar refractory metal alpha second phase. The nominal composition of the base alloy is 8 weight percent aluminum, 27 weight percent molybdenum, balance nickel. Minor elemental additions may be made to modify the mechanical properties of the first phase and/or the second phase. The directionally solidified alloy of the invention is characterized by exceptional anisotropic tensile properties, high isotropic ductilities, combined with good oxidation resistance and satisfactory sulfidation resistance at elevated temperatures.
