The crystallography and microstructure of eutectic carbides crystallizing in non-equilibrium conditions in hypoeutectic Fe24Cr0.8C have been studied by light microscopy, scanning electron microscopy, and transmission electron microscopy. The alloy was synthesized in an arc furnace in high purity argon atmosphere and crystallized on water-cooled copper mould. Greater thermal gradient in regions close to water-cooled, copper mould in comparison with top of the ingot gives a formation of eutectic carbides with two morphologies: large polygonal carbides and surrounding them much smaller, plate-like carbides instead of rod-like carbides, observed in top of the ingot. There was no evidence for influence of non-equilibrium crystallization to the formation of types of carbides different than M₂₃C₆.
