STUDY OF DIRECTIONALLY SOLIDIFIED Fe - 4,25 %C EUTECTIC ALLOY USING ELECTRON BACKSCATTER DIFFRACTION (EBSD) TECHNIQUE

摘要

Electron back-scattered diffraction was used to determine the microstructure of a eutectic. Fe - 4,25 % C alloy was directionally solidified with the growth rate of 300 mm/h (83,3 um/s) in a vacuum Bridgman-type furnace with liquid metal cooling. Eutectic phases have been observed using optical microscopy and scanning electron microscopy. The morphology of the eutectic phases was described. EBSD analysis reveals pronounced direction <100> of ce-mentite in the microstructure produced by directional solidification.
