AB - TiC/Fe-Al cermets were produced by the mechanical alloying and sintering process. The composition of the binder phase was designed to be Fe-28 at%Al with TiC of 50, 70 and 90 vol %. Mechanical alloying of elemental powders of Ti, C, Fe and Al promoted the formation of the supersaturated TiC solid solution containing Fe and Al. During sintering Fe3Al phase precipitated from the supersaturated TiC solid solution. Relative densities of sintered bodies were in the range from 98.3% to 95.1% as the volume fraction of TiC increased from 50% to 90%. Microstructures of sintered bodies containing TiC of 50 vol% and 70 vol% were consisted of three regions; 1-2 µm TiC particles, Fe3Al binder with 100 nm TiC particles and particle-free Fe3Al regions. And the sintered body containing 90 vol% TiC was consisted of two regions of TiC and particlefree Fe3Al. Indentation test results showed that Fe3Al with 100 nm size TiC particles and particle-free Fe3Al regions are effective for the prevention of crack propagation. The bending strength of 50 vol% and 70 vol% TiC/ Fe3Al cermets was higher than 1700 MPa.
