Abstract:Al/TiC composites were synthesized by the thermal explosion mode of self-propagating high-
temperature synthesis (SHS) from Ti, C and Al powders. The effects of the heating rate on the ignition temperature, the combustion temperature, the phase composition, the relative density and the microstructure of the products were studied.
Key words: heating rate SHS Al/TiC composites
