Conclusions
An experimental study was made of the process of densification of a binary titanium-chromium diboride powder. The dependence of the relative density of hot-pressed specimens on temperature, applied pressure, and pressing time was determined. An analysis of experimental data carried out within the framework of the theory of volume viscous flow of a porous solid has shown that densification in the hot pressing of a binary titanium-chromium diboride powder is effected through creep of its particles. The creep is controlled by the dislocation climb mechanism. Determinations were made of specific rates of steady-state creep for the particles of the binary titanium-chromium diboride powder; the specific rate of steady-state creep was found to be proportional to the square of stress. The energy of activation for steady-state creep of the binary titanium-chromium diboride powder was calculated.
