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”

Key words: metallic materials rapid solidification Fe--Co alloy undercooled competitive nucleation metastable phase
