Abstract

Abstract

The behavior of nitride inclusions during the VIM, VAR and ESR processes of superalloys has been investigated. The experimental results have proved that the inclusions in the original metals, even if the pure TiN power added rapidly decompose at the superalloy liquid processing temperature and the nitrides in the remelted metals are mainly precipitated from solution during the sulidification process.
