Summary

Phase selection processes in undercooled Fe-Cr-Ni melts have been investigated with respect to the competitive formation of ferrite (bcc) and austenite (fcc) using the electromagnetic levitation technique and drop tube experiments of atomized particles. In the austenite regime of the isoplethal section Fe69Cr31-xNix (x > 12 at%) metastable bcc formation was observed which is selected by nucleation. In the ferrite regime metastable fcc phase formation was found in undercooled melt drops solidified on chill substrates. It is ascribed to the preferred dendrite growth of the metastable austenite.
