The structural aspect in the stress state of the surface layer of the nitride ceramic

The significant influence of the shape of titanium carbide grain on stress state of the surface layer of nitride ceramics under the action of distributed load is showed. The effect of an influence depends on structural elements. In the intergranular phase and the matrix, the more favorable stress state in the nitride ceramics with round shape of TiC–grain, and grain surface in ceramics with of elliptical shape grain.

Keywords: nitride ceramics, grain, surface layer, stress state, distributed load..
