en Research Paper Research Paper <p>Combustion synthesis is a special thermophysico-chemical process applied for production of intermetallic compounds. In the present work, a reaction–diffusion numerical model was developed to analyze the combustion synthesis of aluminide intermetallics by self-propagating high-temperature synthesis process. In order to verify the reliability of the numerical model, an experimental setup was designed and used to perform the combustion synthesis of nickel and titanium aluminides. The developed model was further used to determine the temperature history of a powder mixture compact during self-propagating high-temperature synthesis. The effect of compact relative density on combustion temperature and wave propagation velocity was also studied.</p> Combustion synthesis (CS), Aluminide intermetallic compounds, Modeling, Porosity 1 5 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-3-120&slc_lang=en&sid=1 M.
