Abstract
Up to five solidification pathways were revealed in solidification of undercooled Co79.3B20.7 alloy. As the undercooling prior to nucleation increases, the primary phase changes from Co3B to Co2B to Co23B6 and then to α-Co/Co3B eutectic. In the case that Co23B6 forms as primary phase, the alloy may completely solidify into Co23B6 or the primary Co23B6 phase is subsequently remelted and resolidified into α-Co/Co2B eutectic. Based on nucleation theories the phase competition was interpreted.
