Abstract

The technique of analytical forecasting the melting technology of multicomponent niobium alloys based on the relationship between physico-chemical, thermophysical properties and features of alloys refining is presented. It is confirmed by the features of the formation the dendritic cast structure and dendritic liquation in experimental samples of the Nb-Ti-Al system alloys with the Cr, Zr, Mo, Si. The technological scheme of melting alloys in industrial conditions with the full use of production waste is recommended.
