ABSTRACT:
An improved columnar grained, polycrystalline, anisotropic article is provided of a Ni-base, carbide fiber reinforced eutectic alloy by a method of providing a unidirectionally solidified cast body which includes such fibers aligned and embedded in a gamma-gamma prime structure. Such body is heated at a first temperature to fully solution the gamma-gamma prime without melting the carbide fibers; exposed to a second, lower, temperature to precipitate fine gamma prime in substantially cuboidal shape within the size range of 1-4 microns; and exposed to a third, still lower, temperature to perfect such cuboidal structure without refinement or coarsening. The resultant article is characterized by improved longitudinal stress rupture life.
