Both materials exhibited rising R-curve behavior, The Si3N4-TiN composites, however, displayed better damage tolerance and higher resistance to crack growth. From TEM observation, it was inferred that this superior performance of Si(3)N4-TiN composites can be attributed mainly to stress-induced microcracking at heterophase (Si3N4/TiN) boundaries.
