Mechanical alloying (MA) has been used to synthesize Ti 3 SiC 2 powder from the elemental Ti, Si, and C powders. The MA formation conditions of Ti 3 SiC 2 were strongly affected by the ball size for the conditions used. MA using large balls (20.6 mm in diameter) enhanced the formation of Ti 3 SiC 2 , probably via an MA‐triggered combustion reaction, but the Ti 3 SiC 2 phase was not synthesized only by the MA process using small balls (12.7 mm in diameter). Fine powders containing 95.8 vol% Ti 3 SiC 2 can be obtained by annealing the mechanically alloyed powder at relatively low temperatures.
