Conclusions
-
1.
A process, consisting of impact compression and subsequent heat treatment (heating to 850°C and holding at temperature for 50 min), has been developed for the production of nickel base composite material reinforced with knitted-weave gauzes from 0.03-mm diameter tungsten fibers.
-
2.
The short-time strength of the composite material at 800, 950, and 1100°C markedly exceeds that of its matrix. Thus, reinforcement increases the strength almost six times at 950°C and 12 times at 1100°C. At the same time, the ductility properties of the material decrease.
-
3.
After heat treatment, thermal stresses due to the difference in linear expansion and elastic constants between the components were detected in the composites investigated.
