Abstract
Ni-base alloy foils are made directly from Ni-base alloy powders by hot pressing. These Ni-base alloy foils are characterized by having a thickness of 0.017 in. or less, and by the fact that they are fine-grained and substantially free of oxygen, nitrogen and deformation-induced defects. The as-pressed Ni-base foils are generally ductile and adapted for subsequent forming operations, including cold rolling. The reduction in thickness imparted in a single pass to a Ni-base alloy foil through cold-rolling ranged from 4-10% depending on the alloy composition. The total reduction in thickness ranged from about 10-50% based upon a plurality of such passes. For reductions in thickness greater than about 10%, annealing is employed for stress relief.
