Essay

The dissertation is focused on the development of the new technologies for the refinement of corrosion resistant superalloys waste, including non-conditional waste, using the techniques of the directed crystallization in vacuum and the combined vacuum induction and electron beam melting. In the course of the directed crystallization, the refinement is ensured by the accumulation of nonmetallic inclusions in the front of crystallization surface in the upper part of the billet, which is later mechanically removed. At the combined melting the refinement of nonmetallic inclusions is performed by means of their evaporation due to the effect of the electron beam, with the charge melted and the melt overheated by the induction heating. To obtain blades and vanes from waste, two stage technological schemes are proposed. In the first stage the waste is refined by the directed crystallization or combined melting resulting in charge billets production, while at the second stage these billets are re-melted by thecombined melting with further blades and vanes casting.
