The purpose of this study was to produce Fe 3 Al/TiC-SiC nanocomposite by mechanical alloying of the FeSiTiO 3 , Al and C powder mixture. The phases made of the samples were characterized by XRD. The morphological evolution was analyzed during mechanical alloying by FESEM. The particle size of the 30 h milled powder was determined by TEM. The results showed that ball milling led to the formation of SiC after 10 h. Increasing of milling time to 20 h caused TiC x and Fe 3 Al were formed with remained TiO 2 phase. After 30 h milling, all peaks of TiO 2 phase eliminated and Fe 3 Al/TiC-SiC nanocomposite was formed. The XRD investigation of the powders after annealing showed that no new phases were formed. TEM image confirmed that average particle size of syntehsized powder after 30 h milling was 60 nm.
