Investigations of the effect of the initial liquid phase state on the processes of solidification in Fe50Cr15Mo14C15B6 bulk-amorphized melts have been carried out by differential thermal analysis, X-ray structural analysis, metallography and viscosimetry. The anomalies caused by changing the relation of the atom microgroups of boride and carbide types have been discovered for the first time in polytherms of the melt viscosity in the vicinity of 1653 K and 1793 K. The structural changes observed in the liquid phase result in anomalies in the Fe50Cr15Mo14C15B6 melt supercooling behaviour and a change in the crystallization mechanism. Structural transformation temperatures, can be considered to be an additional factor in the search for promising alloys with optimized glass forming abilities and enhanced service properties.
