Self-propagating high-temperature synthesis of finely dispersed titanium carbide phase of powder mixtures in aluminum melt

Abstract

The process of self-propagating high-temperature synthesis (SHS) of titanium carbide particles in aluminum melt containing the mixture of titani- um and carbon powders with addition of chloride-containing flux, aluminum or halide salt (Na 2 TiF 6 ) powders in it has been investigated in produc- ing Al–10%TiC composite alloy. The use of the additives is shown to allow diminishing the size of synthesized TiС carbide phase particles to ultrafine (0,17–0,35 μm) and nanosized (less than 0,1 μm) levels.
