Effect of Al2O3 content on the synthesized products by the laser ignited self-propagating high-temperature synthesis reaction of Al2O3-Ti-C system

► The ignition temperature increases and the combustion temperature decreases with the increasing of Al2O3 content. ► The sintered density decreases and the porosity increases with the increasing of Al2O3 content. ► TiC particle size decreases with the increasing of Al2O3 content. ► The fracture type of the sintered specimens is the nearly completely intergranular mode.
