First-principles study on the structure, fracture toughness, and thermodynamic properties of a new-designed Co30Ni30 Fe20Cr20 high-entropy alloy

First-principles study on the structure, fracture toughness, and thermodynamic properties of a new-designed Co30Ni30 Fe20Cr20 high-entropy alloy

In this work, the structural stability, fracture toughness, and thermodynamic properties of Co30Ni30Fe20Cr20 high-entropy alloy (HEA) has been investigated by using first-principles calculations combined with special quasi-random structures. The calculated lattice constant of 3.485 Å was in good agr...
