Abstract

Fe-Co single-phase alloy melts with different Co contents were undercooled using fluxing method. The maximum undercooling ΔT = 457K (relative undercooling ΔT/Tm=0.259) was achieved in this work. At low undercooling (ΔT), single-phased microstructure was observed, but metastable bcc phase emerged in the as-solidified microstructure once ΔT exceeded a critical value, ΔTcrit In the presence of classical nucleation theory, phase selection in the undercooled Fe-Co melt was investigated, and the theoretical calculation was coincided with the experimental result.
