This paper presents experimental results on thermophysical properties of the most commonly used titanium alloy, Ti-6Al-4V, in its solid phase. The subsecond pulse calorimetry has been applied for measuring heat capacity, specific electrical resistivity, and hemispherical total and normal spectral emissivity, and the laser flash method for measuring thermal diffusivity. Specific heat capacity and specific electrical resistivity were measured from 250 to 1 700 K, thermal diffusivity from 190 to 1 530 K, hemispherical total emissivity from 780 to 1 670 K, and normal spectral emissivity at 900 nm from 1 300 to 1 730 K. Thermal conductivity and Lorentz function were computed from experimental data in the range from about 190 to 1 530 K. For necessary corrections literature data on thermal linear expansion were used. The results obtained are compared with available literature values.
