Transformations of Nonmetallic Inclusions in Steels Subjected to High-Temperature Heating

We study the mechanism of dissolution of nonmetallic inclusions under the conditions of high-temperature heating. It is shown that the dispersion of inclusions is associated with several processes (dissociation and partial dissolution of the inclusions, their diffusion fragmentation in the course of...

Summary:We study the mechanism of dissolution of nonmetallic inclusions under the conditions of high-temperature heating. It is shown that the dispersion of inclusions is associated with several processes (dissociation and partial dissolution of the inclusions, their diffusion fragmentation in the course of selective dissolution and the formation of dispersed “satellite” particles). We also discuss the specific features of the formation of microcomposite zones near inclusions.
