During reactive sintering production of intermetallic compounds, the thermally-activated reactions usually proceed very rapidly. Therefore the description of the reaction mechanisms is a challenge for current scientists. This work presents four approaches, how to succeed in this task. Thermal analysis, reaction front quenching method, in situ diffraction analysis and process modelling are described.

Keywords: reactive sintering, powder metallurgy, microscopy, phase analysis, thermal analysis
