Abstract
TiC particles were prepared in situ by self-propagating high-temperature synthesis (SHS) reaction in the Fe–Ti–C elemental powder mixture. The reaction behavior and formation route of synthesizing TiC in the Fe–Ti–C system were investigated. With Fe contents increasing, the adiabatic temperatures, reaction temperatures and TiC particles sizes obviously decreased. The addition of Fe promotes the reaction between Ti and C through a “bridging” effect. Fe plays an important role in controlling the reaction behavior and morphology of products, serving not only as a diluent to inhibit the TiC particles from growing, but also as an intermediate reactant to promote the reaction.
