“…However, this configuration constitutes no more than 0.1% of the total atoms. Upon closer inspection, sporadic structures resembling a rhombohedral symmetry, reminiscent of the laves phases and µ-phase (D85 structure), were observed in the vicinity of GB in models containing Nb, Mo, and W. Experimental observations of the µ-phase have been documented in FeCo-Nb alloys, particularly those with a high Nb content [232]. This can be rationalized by the inherent formation of these compounds in the composing binary alloys, namely Fe-Nb [178][179][180][181][182], Fe-W [191][192][193],…”
