Summary

Melts of Fe32.5Si67.5 alloy were containerlessly processed using electromagnetic levitation technique. In comparison of the surface morphology as well as the microstructure morphology at different undercoolings, transition in growth mode for the primary phase, α, from faceted growth type to nonfaceted growth type with increase of the undercooling is proved. At the undercooling of 260 K, β-FeSi2 phase is directly formed from the undercooled melt. The eutectics tended to grow into lamellar form but with one phase taking the form of short rods within the layer it appeared. Reduction of the eutectic spacing is also presented to be directly influenced by the undercooling.
