ДИСПЕРСИОННОЕ МОДИФИЦИРОВАНИЕ ДЕНДРИТНОЙ СТРУКТУРЫ МЕТАЛЛА СВАРНЫХ ШВОВ

The paper deals with the effect of dispersed particles of refractory compounds (Al2O3, MgO, ZrO2) added as cold filler to 1.6 mm flux-cored wire, on modification of the dendritic structure in low-alloyed weld metal of C-Mn-Cr-Ni-Mo-Si-Cu system of K65 strength class. Obtained results do not allow making an unambiguous conclusion on the mechanism of the effect of refractory oxides on dendritic structure modification. 5 Ref., 6 Tabl., 14 Fig. [ABSTRACT FROM AUTHOR]
