Phase transformations in 0.34С–1Cr–1Ni–1Mo–Fe steel under the action of electrolytic plasma nitrocarburizing

Changes in the phase composition of 0.34С–1Cr–1Ni–1Mo–Fe steel during electrolytic plasma nitrocarburizing are studied via TEM. It is found that nitrocarburizing leads to considerable changes in the steel’s structure (phase composition, number of existing phases, and morphology).
