Conclusions
-
1.
The sintering of specimens from, a mixture of tungsten and molybdenum powders takes place by the diffusion mechanism at temperatures at which the values of the coefficients of mutual diffusion attain 10−9−10−8 cm2/sec.
-
2.
An addition of up to 0.5% nickel activates the sintering of W-Mo specimens at 1200° C and enables a relative density of 90% to be attained after holding for 1 h.
-
3.
During the activated sintering of W-Mo specimens, no solid solution formation was observed. It is probable that the dislocation mechanism is chiefly responsible for densification during activated sintering.
