Oxide dispersion strengthened alloy foils |
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.
