Embodiments disclosed herein related to superalloy compositions and applications using the same. The superalloy compositions disclosed herein including at least one ternary intermetallic compound having a general chemical composition of AZ[BXCY]. Base element A is selected from the group consisting of cobalt, iron, and nickel; and element B and element C are independently selected from different members of a group consisting 40 elements of the periodic table. Base element A, element B, and element C are each different elements. Z is about 2.1 to about 3.9. X and Y are about 0.1 to about 1.9. Additionally, the at least one ternary intermetallic compound of each of the superalloy compositions exhibits the face-centered cubic structure L12. The at least one ternary intermetallic compound of each of the ternary superalloy compositions may exhibit a theoretical formation enthalpy and a decomposition energy less than Co3[Al, W].
