Title: Synergistic stabilization of metastable Fe 23B 6 and γ-Fe in undercooled Fe 83B 17

Abstract

Previous investigations of undercooled liquid Fe 83B 17 near the eutectic composition have found that metastable crystalline phases, such as Fe 23B 6, can be formed and persist down to ambient temperature even for rather modest cooling rates. Using time-resolved high-energy x-ray diffraction on electrostatically levitated samples of Fe 83B 17, we demonstrate that the Fe 23B 6 metastable phase and fcc γ-Fe grow coherently from the undercooled Fe 83B 17 liquid and effectively suppress the formation of the equilibrium Fe 2B + bcc α-Fe phases. Here, the stabilization of γ-Fe offers another opportunity for experimental investigations of magnetism in metastable fcc iron.
