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 3AlF 6) and 3) after the introduction of MS with calcium carbide (CaC 2). 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 3AlF 6 or CaC 2) 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.
