摘要：

The phase composition and microstructure of Ti-Nb alloy produced from composite titanium and niobium powder by selective laser melting (SLM) was studied. Produced monolayered Ti-Nb alloy enhanced the formation of fine-grained and medium-grained zones with homogeneous element composition of 36-38% Nb mass interval. Alloy phase composition responded to beta-alloy substrate phase (grain size was 5-7 mu m) and non-equilibrium martensite.alpha ''-phase (grain size was 0.1-0.7 mu m).alpha ''-phase grains were found along. beta-phase grain boundaries and inside grains, including decreased niobium content. Alloy microhardness varied within 4200-5500 MPa.
