The grain refinement mechanism of undercooled single-phase Fe 70 Co 30 alloy was investigated. With increasing the initial melt undercooling (DT), the first grain refinement occurs within 22 KoDTo87 K, and the second one if DT4183 K. Applying a dendrite break-up model (i.e. on the basis of morpholog
