Fabrication of Al–TiN (10, 30 wt.%) composites by a powder metallurgical route has been investigated using pressureless sintering and hot pressing techniques. Results indicate that sintering followed by hot pressing is required for significant densification and improvement of mechanical properties. The presence of titanium nitride (TiN) particles at grain boundaries played a significant role in improving the densification, and results in improved mechanical properties. Dry sliding wear results showed improved wear resistance of the composite (Al–TiN) compared to the base material (Al) metal due to presence of TiN particles. The wear rates of the Al–TiN composites decrease by an order of magnitude after hot pressing.
