DOI: 10.1002/adem.202500879

Abstract: Eutectic high‐entropy alloys (EHEAs) exhibit unique microstructures and excellent mechanical properties, but their composition discovery has largely relied on trial‐and‐error methods. Although the Calculation of Phase Diagrams (CALPHAD) method can predict eutectic points accurately, it… read more here.
