Abstract
Directionally solidified samples of an Fe‐Fe3C white eutectic alloy were produced in a vacuum Bridgman‐type furnace to study their eutectic growth with pulling rates of 300, 450, and 600 mm/h and a constant temperature gradient of G = 33.5 K/mm. The interphase spacing was measured on these samples, and the samples were X‐ray investigated. A quantitative evaluation of the microstructure EBSD was made. Research was performed with the application of optical an optical microscope, SEM, and computer software for an image analysis of the NIS‐Elements. The dependence between parameter v and the interphase spacing was presented. For the white eutectic, an equation, that resembles the well‐known in the Jackson‐Hunt theory for a regular eutectic, was obtained, but it differed by two terms in equation This may confirm that the studied eutectic belongs to the anomalous class and is a quasi ‐ regular eutectic.
