Results of investigation of non-metallic-inclusions’ behaviour and transformation of interphase inclusion—matrix boundaries under high-energy treatments (hot deformation, laser treatment, high-temperature annealing) are summarized. Principles of inclusion—matrix-boundaries’ slip under different regimes of hot deformation are studied. Plastic behaviour of these boundaries for the different types of non-metallic inclusions is discussed. Features of interaction of non-metallic inclusions and steel matrix during the process of inclusion—matrix-boundaries’ transformation and formation of gradient and composite structures near these boundaries under laser treatment are investigated. The influence of laser-treatment regime on the local hardening of steels is shown. Features of inclusion—matrix-boundaries’ transformation in process of dissolution of non-metallic inclusions under high-temperature annealing are studied. Features of formation of gradient and composite structures near these boundaries under high-temperature annealing are investigated. Possibilities of high-energy treatments influence on structure, width and degree of hardening of interphase inclusion—matrix boundaries and on sizes, composition and distribution of non-metallic inclusions in steels are shown. It makes possible the increase of such treatments’ efficiency.

Key words: steel, non-metallic inclusion, inclusion—matrix boundary, hot deformation, laser treatment, high-temperature annealing.
