Title: FCC MATERIALS OF ALUMINUM, COBALT, CHROMIUM, AND NICKEL, AND PRODUCTS MADE THEREFROM
Abstract:
The present disclosure relates to new materials comprising Al, Co, Cr, and Ni. The new materials may realize a single phase field of a face-centered cubic (fcc) solid solution structure immediately below the solidus temperature of the material. The new materials may include at least one precipitate phase and have a solvus temperature of at least 1000°C. The new materials may include 2.2 - 8.6 wt. % Al, 4.9 - 65.0 wt. % Co, 4.3 - 42.0 wt. % Cr, and 4.8 - 88.6 wt. % Ni. In one embodiment, the precipitate is selected from the group consisting of the L12 phase, the B2 phase, the sigma phase, the bcc phase, and combinations thereof. The new alloys may realize improved high temperature properties.
