Plasticity Origin of Heterophase Inclusions at Steel Forming

Plasticity of heterophase nonmetallic inclusions of various types at hot and cold steel forming was studied. Transformation features of inclusions possessing different phase composition and structure were shown. Inhibiting effect of the second phase of inclusions on the formability of plastic phases at hot and cold strain of the steels was determined. Interaction features of the components of inclusion phases were studied, such as interactions in the inclusion–matrix interfaces and internal phase boundaries in inclusions. Features of the plasticity origin of heterophase inclusions possessing various compositions and structures were discussed.
