High entropy alloy-based compositions and bond coats formed therefrom

Abstract

A high entropy alloy-based composition is provided that has the formula: (M1aM2bM3cM4dM5eM6f)CrAlY1-x-zZrxMoz where: each of M1, M2, M3, M4, M5, and M6 is a different alloying element selected from the group consisting of Ni, Co, Fe, Si, Mn, and Cu such that none of M1, M2, M3, M4, M5, and M6 are the same alloying element; 0.05≤a≤0.35; 0.05≤b≤0.35; 0.05≤c≤0.35; 0.05≤d≤0.35; 0.05≤e≤0.35; 0≤f≤0.35; a+b+c+d+e+f=1; 0≤x≤1; 0≤z≤1; and 0≤x+z≤1.
