Conclusions
-
1.
A study was made of the effect of temperature on the mean size and the density and type of distribution of grains in the hot pressing of molybdenum carbide.
-
2.
Raising the hot-pressing temperature in the range 1900–2200°C at constant process pressure and time is accompanied by an appreciable growth in the mean size of Mo2C grains. At the same time, both the symmetry of grain size distribution and the grain size spectrum increase.
-
3.
The energy of activation for the growth of Mo2C grains, which has been found to be 49 ± 3 kcal/ mole, characterizes collective recrystallization for pressing under the conditions employed.
