Abstract

The self-propagating high temperature synthesis (SHS) was used to fabricate Ti-Si intermetallic phases. The phases were synthesized by the exothermic reaction between Ti and Si powders with proportions corresponding to the composition of Ti3Si, Ti5Si3, Ti5Si4, TiSi and TiSi2 phases. The XRD method was used to analyze the phase composition. The process resulted in formation of Ti5Si3, Ti5Si4, TiSi and TiSi2 phases. A Ti3Si phase did not occur in any produced specimens. XRD analysis showed that substrates can react with graphite mold, creating the phases containing carbon. Effect of Ti particles granulation on the phase composition was also analyzed. The results for samples fabricated by using coarse-grained Ti particles showed that this element has not reacted completely, while reducing of the granulation led to complete reaction.
