POWDER WIRE FOR MICROALLOYING OF STEEL BY VANADIUM

摘要

FIELD: metallurgy; microalloying of steel by vanadium. ^ SUBSTANCE: proposed powder alloy has steel envelope and filler made from powder-like alloy of iron-vanadium-aluminum system; content of vanadium and aluminum is 50-85% and no more than 2.5%, respectively. Space factor of wire is 0.75-0.77. ^ EFFECT: reduced amount of admixtures, aluminum in particular; increased linear mass of filler; wide range of steels. ^ 1 tbl
