Abstract

The proposed article is devoted to the study of the interaction of rare earth metals with basic elements and non-metallic compounds in iron-carbon alloys. The article discusses the method of modifying iron-carbon alloys with rare-earth metals, the nature and mechanisms of interaction of alloy components. The influence of rare earth metals and non-metallic mixtures on the properties of the material is analyzed. The qualitative composition of nonmetallic inclusions formed in steel grades 09G2FB and 17G1SU modified with yttrium and without the introduction of yttrium-containing material (SIITMISH-1) was studied by the X-ray spectral method. With the formation of complex compounds by the introduction of rare earth metal, as a result of which the alloy is purified from non-metallic compounds. Research in this area makes it possible to develop new materials with improved characteristics and optimize the processes of their production and processing
