Structural-phase composition of the Fe-contained alloyed, modified with ultraand nanodispersed powders of d-metals oxides
Methods of X-ray analysis and scanning electron microscopy were used to study iron GL25 in tree states: 1) without the addition of a modifier mixture (MS); 2) after the introduction of MS (mixture of ultra- and nanopowder metal oxides d-metals with a reducing cryolite (Na <sub>3</sub>AlF <sub>6</sub>) and 3) after the introduction of MS with calcium carbide (CaC <sub>2</sub>). The element composition, phase composition, microstructure studied metal matrix and graphite inclusions. It was established that the introduction of the modifying mixture with a reducing agent (Na <sub>3</sub>AlF <sub>6</sub> or CaC <sub>2</sub>) leads to a morphologically homogeneous structure, changes in the phase composition, the content of the volume fraction of the phases, the crystal lattice of solid solutions.
