DOIAbstract
International audienceTi₂AlC-Ti₃AlC₂/Al₂O₃ samples have been successfully synthesized by aluminothermic reduction of TiO₂ in the presence of C. Phase composition of resultant products obtained at different Al excess was characterized by XRD. Microstructures of the samples were observed by SEM. XRD analysis proved that it is possible to improve the yield of MAX phases using Al excess. With increasing Al excess, a major MAX phase was found to change from Ti₂AlC to Ti₃AlC₂
