The effects of initial density, composition mixture ratio, and particle size on thermal conductivity of titanium and graphite powder mixture compact has been experimentally investigated and a thermal conductivity model has been developed. Thermal conductivity values have been measured for compact densities ranging from 45percent to 77percent of maximum theoretical density and for Ti/C mixture ratio by weight ranging from 0.7 to 1.3. The model predicts that, for an increase in density, thermal conductivity increases but it decreases with an increase of Ti/C mixture ratio. The experimental results also show the dependency trend of thermal conductivity on particle size of the constituents.
