“…This has been proven to be of significant mportance in designing new MPEA systems, as the stability of the random solid solution is of paramount importance. 101 , 102 , 103 , 104 Extensive thermodynamic databases have been developed to streamline this process. An iterative process was employed to search among more than a million alloys within the Al-Co-Cr-Cu-Fe-Ni system and progressively fabricated a total of 42 new MPEA candidates that were predicted to possess high hardness to expand the training dataset.…”
