Evaluation of Physical and Mechanical Properties of Structural Components of Ti-Nb Alloy

By the results of X-ray analysis, microstructural analysis, nanohardness and elastic modulus measurements it was defined that non-equilibrium phases during the process of crystallization are formed in the titanium-niobium alloy with 40 mass.% of Nb. The minimum of non-equilibrium phases is formed at the Ti-40 mass.% Nb alloy. The uniform grain structure, which consists of beta-phase grains with the minimum of elastic modulus, is formed in the alloy ingot. Such structure and complex of properties allows using this alloy for severe plastic deformation.
