Conclusions

In (Ti, W)C-Co alloys with binder contents of 30 and 8% the main carbide particle growth mechanism during liquid-phase sintering withing the limits of applicability of Wagner's theory is apparently recrystallization through the liquid phase. In the later stages of sintering an 8% Co alloy can probably exhibit also coalescence. The controlling stage of the recrystallization is diffusion through the liquid phase. In the range of liquid-phase sintering times investigated (1–10 h) the carbide particles in (Ti, W)C-30% Co and (Ti, W)C-8% Co alloys form well-developed skeletons. Small variations in the structure of these skeletons can be brought about by changes in grain size. Changes in the specific surfaces (contact, phase, and total surfaces) of these alloys are in good agrement with the findings of theoretical investigations into the effect of sintering on interfacial areas.
