The manuscript presents results of Young's modulus (E) measurements for two-phase titanium alloy Ti-6Al-4V. The estimation of elasticity modulus (E) was made using three independent methods: standard mechanical tests (tensile test) on an electronic dynamometer “Instron”, the method measurement of sound speed propagation and the method of nanoindentation using nanohardness – testing scanning machine “Nanoscan3D”. The elastic properties were studied for Ti-6Al-4V alloy in different structural states: nanostructured (NS), microcrystalline (MC) and coarse-grained (CG). The elastic modulus α - and β - phases were measured by means of nanoindatation methods. It is shown that a value of elasticity modulus E for the Ti – 6Al – 4V alloy in the CG state is less than in the NS state by more than 20% that is likely to be attributed to the change in amount ratio between α and β phases characterized by different elastic properties.
