Formation of titanium silicon carbide (Ti 3 SiC 2 ) by mechanical alloying (MA) of Ti, Si, and C powders at room temperature was experimentally investigated. A large amount of granules less than 5 mm in size, consisting of Ti 3 SiC 2 , smaller TiC particles, and other silicides, have been obtained after ball milling for only 1.5 h. The effect of excess Si in the starting powders on the formation of Ti 3 SiC 2 was studied. The formation mechanism of Ti 3 SiC 2 was analyzed. It is believed that a mechanically induced self‐propagating reaction is ignited during the MA process. A possible reaction mechanism was proposed to explain the formation of the final products.
