Abstract

The aim of this work was to study the microstructure and high-temperature phase transformations of the Fe71.25Si9.5B14.25In5 alloy. The alloy was remelted in a resistance furnace, and a sequence of melting and crystallization at a range of high temperatures was observed using a mid-wave infrared MWIR camera. The alloy was also investigated by differential thermal analysis (DTA). The microstructure of the alloy was studied using a scanning electron microscope SEM with an energy dispersive spectrometer (EDS). The results show that there is a clear partition into two liquids in the studied alloy. The ingot microstructure presents very strong segregation into the eutectic regions enriched in the Fe-Si-B and In-rich regions.
