Abstract
Thermal conductivities of titanium hydride and deuteride (TiHx and TiDx: 1.64≤x≤1.98) in the temperature range from room temperature to 570 K have been calculated from the relation of thermal diffusivities, which are measured by means of a laser flash method, the literature data of their densities and specific heats. The calculation results showed that the thermal conductivities of TiHx and TiDx increased with increasing temperature and composition and were higher than that of Ti. On the basis of Wiedemann-Franz rule, the heat conductions due to electrons and phonons have been estimated from the temperature and composition dependences of the thermal and electrical conductivities measured using a four-contact DC method. Both phonons and electrons play an important role in the thermal conductivities of TiHx and TiDx at 570 K.
