TECHNOLOGY DESCRIPTION
Titanium aluminide alloys (TiAl) combine high temperature resistance and low density. However, these alloys are brittle and have a limited creep resistance. Finally their manufacturing processes are complex and expensive.
- Manufacturing process by Spark Plasma Sintering (SPS) of high performance alloys
->Optimized conditions for SPS densification
-> Original powder composition including titanium aluminide
- Properties of the material obtained (IRIS-SPS)
->Outstanding creep resistance at service high temperature
-> Good ductility at room temperature making assembly and maintenance easier
- Near net shape manufacturing
- No post heat treatment required
BENEFITS
- Unmatched compromise resistance/ductility at high temperature
- Homogeneity of microstructures
- Near net shape
- Reproducibility of material
- No heat treatment
- Rapidity of manufacturing
- Cost reduction
