In this paper, thermal properties of two titanium-titanium boride composites were processed by spark plasma sintering, hot-iso-static pressing, and vacuum sintering were characterized. The scanning electron microscopy and X-ray diffraction analysis are used to examine the uniform distribution of the secondary particles in the processed composites. Thermal properties of the composites such as thermal conductivity, specific heat, thermal diffusivity and coefficient of thermal expansion were estimated for the temperature range between 50 and 250 degrees C. The results showed that thermal conductivity, thermal diffusivity, and specific heat were increased with increase in temperature and titanium boride reinforcement. The influence of titanium boride reinforcement and processing technique on thermal properties is also discussed. Thermal properties presented in this paper confirmed that the titanium-titanium composites can be used for thermal, automobile, aerospace, and renewable energy applications.
