Abstract

The R-curve for Si 3N 4-40 wt% TiN composites was estimated by the indentation-strength method and compared to that of monolithic Si 3N 4 with duplex microstructure. Both materials exhibited rising R-curve behavior. The Si 3N 4-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 3N 4-TiN composites can be attributed mainly to stress-induced microcracking at heterophase (Si 3N 4/TiN) boundaries.
