WebMar 1, 2024 · The Fe-Cr-Al phase diagrams and elastic properties are investigated in the following way. The first-principles calculations give the stable phases and elastic properties at zero temperature. Then the results are extended to finite temperature by means of the cluster variation method (CVM) [30], [31] and cluster expansion method (CEM) [32].
