Particularity of formation the cast structure of multicomponent niobium alloys Nb – Ti – Al

Abstract

The features of formation the dendritic heterogeneous cast structure of perspective multicomponent niobium alloys, including highly entropic alloys, which are due to physicochemical i thermophysical characteristics of alloys, are investigated. The preconditionthe necessity and ways for active intervention in the crystallization process for obtaining homogeneous defectless castings are established.
