a Free energy of the candidate precipitates with respect to the solid solution. The percentages for the L21 phase indicate the occupation of the (Co,Ni) sublattice by Co. For each phase, the first, second, and third bars represent the 0 K (−273 °C) energy difference in the ferromagnetic state, the 0 K (−273 °C) energy difference in the paramagnetic state, and the free energy difference at 1150 K (877 °C) with the inclusion of configurational and electronic entropy, respectively. b Densities of states of the L21 phase for different Co contents in the ferromagnetic state. c Schematics of the thermomechanical processing for precipitation-strengthened Al0.2CoNiV alloys. d Phase identification via X-ray diffraction (XRD) analysis of the annealed Al0.2CoNiV alloys.
