Abstract

Employing the method of glass fluxing combined with thermal cycling, hypercooling (ΔT_hyp) up to 460 K was achieved in the bulk Fe₈₃B₁₇ alloy melt. Within the achieved undercooling range, it was found that only one eutectic reaction occurs during rapid solidification. For ΔT_hyp < 386 K, α-Fe + tetragonal Fe₂B phases were detected. For ΔT_hyp ≥ 386 K, a metastable phase Fe₃B was found directly separating from the undercooled melt and remaining at room temperature. In terms of kinetic and structural analysis, phase selection between the metastable phase, Fe₃B, and the stable phase, Fe₂B, was interpreted. By isothermal annealing of the as-solidified samples subjected to ΔT_hyp ≥ 386 K, the metastable-stable transformation correlated with solid-state transformation is investigated.
