SUPERALLOY COMPOSITIONS INCLUDING AT LEAST ONE TERNARY INTERMETALLIC COMPOUND AND APPLICATIONS THEREOF

摘要

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 A_Z[B_XC_Y]. 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].
