Abstract

A searching experiment aimed at identifying appropriate process conditions to form single tracks of titanium and niobium composite powder is reported to be carried out by an SLM experimental facility. SLM conditions were determined and a set of Ti-Nb alloy multilayer samples was produced relying on the experimental results. Macro-and micro-structures, phase composition of multilayer samples were studied. There are fine-and medium-grained zones detected in selective laser melted Ti-40 wt. % Nb (Ti-40Nb) alloy. Phase composition of the alloy is similar to the main phase of titanium and niobium β-phase solid solution (5-7 μm grains) and non-equilibrium martensite α″-phase (0.1-0.7 μm grains). Grains of α″-phase with low niobium concentration are found on β-phase grain boundaries. Relying on measured modulus of elasticity a low-modulus Ti-Nb alloy is reported to be synthesized in the SLM-process.
