Figure 2: Phase stability of AlxCrCoFeNi (0 < x ≤2.0) from first-principles calculations.

From: Atomistic clustering-ordering and high-strain deformation of an Al0.1CrCoFeNi high-entropy alloy

Figure 2

Phase stability of the A1 (FCC) phase relative to A2 (BCC) phase for AlxCrCoFeNi (x = 0.0–2.0, x in mole fraction) as calculated within the KKR-CPA-VP approach. The free energies of A1 and A2 phases are shown by solid-squares (magenta) and solid-circles (red), respectively. The formation of the A1 phase is more favorable than A2 phase for x ≤ 0.5. A common tangent line (red) to free-energy curves shows Al mole-fraction region (0.5 ≤ x ≤ 1.25) over which mixed phase (A1 + A2) exists.
