摘要

High undercooling up to 550K (0.39 T_E) was achieved in eutectic Ni_78.6Si_21.4 melt using glass fluxing combined with the cyclic superheating. According to the microstructure evolution with the initial undercooling, surprisingly, a transition from non-faceted to faceted phase occurs for the as-solidified morphology of the alpha-Ni phase at the undercooling of 390K. On the basis of the entropy of fusion criterion and the interface kinetics, this interesting morphology transition at high undercooling is analyzed.
