Conclusions
The data on the thermal diffusivitya of the titanium-tungsten hard alloys of various composition in the temperature range up to 1400‡K were obtained; the results of measurements of thea values of the components of the alloys were used to examine the effect of the phase components on the total heat conductivity and thermal diffusivity of the alleys of this type.
The differences in the heat conductivity values of the alloys determined by means of the experiments and calculated on the basis of the measured heat conductivities of the phase components are caused mainly by the differences in the composition of the Co-phase and the (Ti, W)C phase of the real alloys in relation to the model used for the calculations.
