N.G. Efimenko
Ukrainian Engineering-Pedagogical Academy, Kharkiv, UkraineAbstract
Refining, modifying and alloying effect of yttrium in cast steel 30 was substantiated using advanced procedures. Mechanism of yttrium effect on cold resistance of pearlitic steels and their welded joints is specified.
Keywords: rare-earth metals, modifying, alloying, refining, steel, colei resistance, internal friction of lattice, dislocations, substructure, Mossbaurer spectra, lattice pitch
