TiN particle size is an effective parameter on microstructure, mechanical and physical properties of SiAlON-TiN composites. In this study, the effect of TiN particle size (nano and micron level) on microstructural evolution, mechanical and physical properties were investigated. The phase and microstructural evolution, SEM and the XRD characterization methods were used to observe the effects of TiN particle size. Indentation fracture toughness and Vickers hardness of the samples were measured in order to evaluate the mechanical behavior. Archimedes principle was used in order to determine bulk density and porosity. Correlation between TiN particle size and hardness, fracture toughness, microstructure, phase evolution was discussed. It was observed that decrease in particle size led to little improvement in fracture toughness and hardness.
