The effect of process parameters on the combustion synthesis of Ti- Al/TiC composite materials

The synthesis of titanium aluminide/titanium carbide composite via the thermal explosion mode of combustion synthesis was studied. Powder mixtures of Ti+Al/Ti+C were pressed to form cylindrical preforms. The samples were heated with a high heating rate in a tube furnace. The occurrence of highly exothermic reactions between Ti and Al as well as Ti and C resulted in the formation of a matrix of titanium aluminides with dispersed particles of TiC. The product was characterized by performing analyses such as XRD and SEM. The effect of Ti+Al:Ti+C ratio on the process behaviour was investigated
