Laser Remelting of a CrMnFeCoNi High‐Entropy Alloy: Effect of Energy Density on Elemental Segregation

open access: yesAdvanced Engineering Materials, EarlyView.
Laser remelting of a CrMnFeCoNi high‐entropy alloy reveals that optimal chemical homogenization occurs between 30 and 40 J·mm−2. Within this range, elemental segregation is reduced by over 30% compared to the as‐cast state. The study establishes this window as a fast, effective alternative to prolonged annealing for achieving uniform elemental ...
