The Spark Plasma Sintering (SPS) route has been explored as a new manufacturing technique to produce turbine blades for high temperature aerospace applications. SPS is a powder metallurgy process where the densification occurs thanks to the application of a uniaxial pressure and a high intensity current. Titanium Aluminides (TiAl) have been successfully densified and optimized leading to the production of an as-SPS material exhibiting outstanding mechanical properties at both room and high temperature. Indeed, a TiAl alloy offering high strength up to 1000°C has been obtained in less than 30min without any subsequent heat treatment. At the same time, a work on densification mechanisms occurring during the sintering and the development of a suitable graphite tool have allowed to densify a TiAl near-net shape blade in one shot.
