Integrated evaluation of effect of yttrium on properties of steel welds

N.G. Efimenko

Ukrainian Engineering-Pedagogical Academy, Kharkiv, Ukraine

Abstract
The refining, modifying and alloying role of yttrium in the metal of low-alloyed welds, depending on its concentration, was experimentally confirmed. Yttrium influence in weld metal is most favourably manifested for its ductile properties and toughness in case of proceeding of the refining and modifying effects.
Keywords: deposited metal, electron microscopy, dislocations, mechanical properties, modifying, nоn-metallic inclusions, multilayer welds, refining, low-temperature embrittlement
