Abstrakt: Various methods of removing sulfur from a complex nickel melt are considered. They are based on the use of slags based on CaO or metallic calcium and the introduction of a rare-earth metal (La, Y) during melting in a vacuum induction furnace. Some properties of alloys (high-temperature strength, long-term strength, ductility) are improved after decreasing the sulfur content. [ABSTRACT FROM AUTHOR]
