    摘要: 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.

    摘要: Oxide dispersion strengthened (ODS) Ni-base alloy foils are made directly from powders of these alloys by hot pressing. These ODS 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 nitrogen and deformation induced defects. The as-pressed ODS Ni-base alloy foils are adapted for subsequent forming operations, including cold rolling. The reduction in thickness imparted in a single pass to an Ni-base alloy foil through cold-rolling was about 8%. The total reduction in thickness was about 55% based upon a plurality of such passes. For reductions in thickness greater than 20%, annealing is employed for stress relief.

    摘要: Two-phase Al--Si alloy foils are made directly from Al--Si alloy powders by hot pressing. These Al--Si 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 Al--Si foils where the primary phase is the Al solid-solution phase are also generally ductile and adapted for subsequent forming operations, including cold rolling. The reduction in thickness imparted in a single pass to an Al-11.6Si alloy foil through cold-rolling was at least about 10%, with up to about 90% reduction in thickness accomplished by a plurality of such passes. These reductions in thickness were accomplished without stress relief annealing, but such annealing may be employed if desirable for microstructural modification.
