Abstract

Two different ways of combining nitrogen in virgin and revert superalloy have been identified. The source of nitrogen in revert superalloy has been ascertained. It is found that nitrogen in scraps of virgin superalloy undergoes a transition from CrN to TiN when these scraps are remelted in VIM furnace. High nitrogen content in revert superalloys causes microporosity formation, that greatly deteriorates tensile and stress rupture properties of superalloys.
