Abstract

Abstract 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 1700 K, thermal diffusivity from 190 to 1530 K, hemispherical total emissivity from 780 to 1670 K, and normal spectral emissivity at 900 nm from 1300 to 1730 K. Thermal conductivity and Lorentz function were computed from experimental data in the range from about 190 to 1530 K. For necessary corrections literature data on thermal linear expansion were used. The results obtained are compared with available literature values.
