The present invention relates to a novel material comprising Al, Co, Ni and Ti. The novel material can realize a single phase field of the face-centered cubic (fcc) solid solution structure just below the solidus temperature of the material. The novel material may include one or more precipitate phases and the solvus temperature may be above 1,100 ° C. The novel material may include 2.1 to 8.4 wt% Al, 4.7 to 60.6 wt% Co, 29.6 to 89.3 wt% Ni, and 3.9 to 9.4 wt% Ti. In one embodiment, the precipitate is selected from the group consisting of Ll 2 phase, B2 phase, Ni 3 Ti phase, and combinations thereof. The novel alloy can realize improved high temperature characteristics. |
