|On-Site Speaker (Planned)
In this work, we use the Spark Plasma Sintering to produce near-net shape turbine blades made in Titanium-Aluminum (TiAl) alloys for airplane engines. We will first explain what advantages this powder metallurgy technique offers for such material and application. We will present the work done toward the experimental validation of our model thanks to a very specific microstructural modification in TiAl used as a marker of the temperature. We will also show the pore distribution mapping made at different stages of the densification. In the second part, we will report the latest results on the densification of two types of turbine blades and discuss the path followed to obtain successful sintering of such complex shapes.
