Conclusions
The sintering of tungsten-copper powder mixtures of low copper content can be intensified by employing tungsten powders of submicron particle size. The process of liquid-phase sintering of very fine tungsten-copper powder mixtures can be quantitatively described within the framework of the theory of local heterogeneous deformation of a polycrystalline solid with allowance for diffusional grain shape accommodation.
