Summary

The pressureless sintering behavior of Ti5Si3 was investigated to determine the viability of consolidating the material by this technique. Processing parameters such as initial particle size, temperature, and processing atmosphere were investigated. High density and small grain size material was produced, but assessment of theoretical density is difficult due to changes in interstitial chemistry which occur during sintering. Density is predicted for varying interstitial nitrogen and oxygen content. Silicon volatilization may occur during sintering in low oxygen partial pressure atmospheres, and this presents additional difficulties in maintaining stoichiometry and accessing theoretical density.
