Description	The character of primary crystallization was investigated on a simple cylindrical sample, crystallizing in a cast-iron mould pre-heated to various temperatures. The experimental research comprised the measurement of temperatures using thermocouples, the evaluation of the experimentally acquired temperature gradients G, and the shift rate of the phase transition interface R. Furthermore, it comprised the determination of the so-called critical values Gcr and Rcr, which are reached by the crystallizing metal in the transition interface where the columnar crystals transform into the equiaxed. The numerical model had been developed to expand the limited experimental capabilities of the evaluation of G and R to every point of the longitudinal section, based on the investigation of the 3D transient temperature field within the system comprising the casting, the mould and ambient. Furthermore, the authors have discovered a new criterion (called the 'temperature-delay' criterion), which predicts the macro-str The character of primary crystallization was investigated on a simple cylindrical sample, crystallizing in a cast-iron mould pre-heated to various temperatures.
