Segregation-guided alloy design via tailored solidification behavior by Ahmet Turnali, Dilay Kibaroglu, Nico Evers, Jaqueline Gehlmann, Lennart Sayk, Nicolas J. Peter, Abdelrahman Elsayed, Mehdi Noori, Tarek Allam, Johannes Henrich Schleifenbaum, Christian Haase

“…Our approach was demonstrated by computationally designing a novel AlxCo25Fe(50-x)Ni25 multi-principal element alloy (MPEA) as a model system, employing a combination of CALPHAD, Scheil, and multiphase-field simulations, and by experimentally validating the resulting microstructure evolution. The lower Al content (x = 10.5) was designated to generate a supersaturated single-phase fcc matrix suitable for heat-treatments to trigger local phase transformations. …”
