The properties of continuous casting products strongly depend on the solidification structure, namely the size of columnar and equiaxed zones and the grain size distribution. The nucleation of an equiaxed grain is mainly determined by the availability of nucleation sites and the presence of an undercooled liquid either at the surface or center of a casting. The experiments described in this paper are aimed at determining the solidification rate of iron-based alloys when they are undercooled in the range between 30°C to 285°C. It was found that the solidification rate varied from 0.15 to 7.5 mm/sec, and, increased with undercooling.
