Obtaining of the polymetallic samples from Ti-Al and Ti-Cu systems by the electron beam additive manufacturing method

Abstract

The structure of polymetallic samples of Ti-Al и Ti-Cu systems obtained by wire-feed electron-beam additive technology in vacuum was studied using optical and scanning electron microscopy and X-ray analysis. The results of research show that during obtaining of polymetals, formation of structure in boundary zones occurs according to corresponding state diagrams. However, due to the small size of the melt bath in relation to metallurgical production, the structure of the finer dispersion structure with greater heterogeneity is formed. In the interaction zone of different metals and alloys it is possible to form both transition structures from solid solutions and intermetallic compounds or mechanical mixtures of initial components and interaction products.
