Some characteristics of phase formation in combustion of powdered titanium-silicon and molybdenum-silicon mixtures

Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

The phase formation processes in Ti−Si and Mo−Si systems were studied, using special markers simulating the behavior of large metal particles after they have passed the combustion front. It is shown that, depending on the combustion temperatures of the mixtures, phases can be formed by joint crystallization from the eutectic melt, or disilicides crystallize first and intermediate phases (Mo5Si3 and TiSi) form by a solid-phase mechanism.
