Surface relief, phase composition and defect substructure of the surface layer of iron specimens are investigated using scanning and transmission electron microscopy after high-energy electroexplosive carburizing treatment. The structure formed is shown to exhibit a conspicuous gradient character resulting from variations in carbon content with the layer depth. It is found out that a liquid melt of the sublayer of nanocrystalline structure is formed at the boundary of the melt pool.
