The evolution of modulated elemental reactants containing alternating layers of carbon and Ti, W, or Mo was studied using differential scanning calorimetry and X-ray diffraction. TiC crystallized at 350 °C from a modulated reactant with a composition near 1:1 with respect to Ti and C. Mo 2 C and W 2 C nucleated at 500 and 600 °C, respectively, from modulated reactants with compositions close to their stoichiometry. No exotherms were observed in samples that had compositions that were not close to the stoichiometries of TiC, Mo 2 C, or W 2 C.
