Abstract
Ti3AlC2 and Ti3SiC2 single-phase MAX phases were obtained by preliminary mechanical activation (MA) of initial mixtures of powder reactants in a high-energy planetary ball mill with subsequent self-propagating high temperature synthesis (SHS). The MA and SHS products were studied by X-ray diffraction and electron microscopy.
