The paper brings the results of directional solidification of Fe-Fe3C eutectic alloy. The Bridgman method with vertical thermal gradient in conducted research was applied. Two values of rate was used for sample movement testing. One sample after solidification, was immediately taken of the cooler. The distribution of thermal gradient in the alloy was determined. The value of thermal gradient in liquid at the solidification front was determined. On the samples, where cementite eutectic was oriented, interphase spacing λ was measured. The results of the dependence between parameters v and λ were presented. The research with application of optical microscope and computer programme to image analysis NIS-Elements was used.

W pracy przedstawiono rezultaty kierunkowej krystalizacji stopu eutektycznego Fe-Fe3C. Wykorzystano metodę Bridgmana z pionowym gradientem temperatury. Zastosowano dwie prędkości przemieszczania próbki. Jedna z próbek, po zrealizowaniu krystalizacji została zamrożona. Określono rozkład gradientu temperatury w stopie oraz wyznaczono wartość gradientu temperatury w cieczy na froncie krystalizacji. Na próbkach przeprowadzono pomiary odległości międzyfazowej λ. Przedstawiono wyniki badań określających zależności pomiędzy parametrami v i λ. W badaniach wykorzystano mikroskop optyczny oraz program do komputerowej analizy obrazu NIS-Elements.
