Technological peculiarities of producing complexly-alloyed alloys of Ti-Nb-Si-Z system of medical purposes are considered. The feasibility of formation of ingots of titanium-based alloys within the relatively narrow ranges of concentrations of alloying components, wt.%: 11…13 Nb; 0.9…1.1 Si; 1.9…2.2 Zr is shown. Structure, phase composition and mechanical properties of mentioned materials in cast state were studied. Ref. 4, Tables 2, Figures 3.

Keywords: electron beam melting; medicine; titanium alloy; niobium; zirconium; silicon
