摘要

Fe-Co melt was undercooled using fluxing method in this work. With increasing the initial undercooling (ΔT), two kinds of dendrites were obtained in the microstructure of undercooled Fe₇₀Co₃₀ alloy at both low and high undercooling ranges. For ΔT < 22 K, the as-solidified morphology is similar to the conventional as-cast dendrite, whereas, for 97 K < ΔT < 173 K, a largely developed fine dendritic morphology is observed. BCT model is used to discuss the two different dendritic morphologies, in combination with a stability analysis of dendrite growth based on the morphological instability.
