Abstract
The rapid solidification of undercooled Fe-Co alloy was investigated by combining cycle superheating and molten fluxing purification technology. The results show that metastable phase nucleated primarily only when the critical undercooling was achieved. After 3 h isothermal annealing in single phase γ region, metastable phase was transferred to stable phase completely. Finally, metastable phase in as-solidified microstructure of undercooled Fe-Co alloys can be described as a result of "competitive nucleation-remelting-extensive growth of γ phase-incomplete solid state transformation".
