Abstract

The field-activated combustion synthesis of the composites Ti5Si3−x Nb (0≤x≤0.35) and Ti5Si3−y ZrO2 (0≤y≤0.3) has been investigated. Composites with x≥0.35 and y≥0.2 can only be synthesized in the presence of an electric field. Although in the absence of a field the systems with x=0.35, y=0.2 and y=0.3 can sustain a non-steady combustion wave, the reaction is not complete. An unstable wave propagates to the middle of the sample and then becomes extinguished. The wave velocity of the Ti5Si3-Nb and Ti5Si3-ZrO2 composites increased slightly with the application of a field.
