The lab is looking for industrial or business partners to integrate the solution under a license agreement.
Description:
A French laboratory involved in materials science, solid state physics and molecular chemistry has developed a new manufacturing process to produce high performance titanium aluminide alloys achieved by spark plasma sintering.
The technology at stake should address applications such as aircraft´s engines turbine blades, turbines for thermal engines, turbochargers, valves and pistions for thermal engines.

Titanium aluminide alloys (TiAI) combine high temperature resistance and low density. However these alloys are brittle and have a limited creep resistance. Besides their manufacturing processes are complex and expensive.

This manufacturing process by Spark Plasma Sintering (SPS) of high performance alloys is based on :
- Optimized conditions for SPS densification
- Original powder composition including titanium aluminide
Properties of the material obtained are:
- outstanding creep resistance at service high temperature
- good ductility at room temperature making assembly and maintenance easer.
This technology does not require post heat treatment.

Technical Specifications:
Secondly creep rate at 700°C/300MPa (megapascal): 3,5 10-9 s-1
Secondary creep rate at 750°C/200MPa: 4,5 10-9 s-1
Plastic elongation at rupture at room temperature: 1.6%
Nominal composition of the alloy: Ti: 49.90; Al:48; W:2; B:0,08
Creep life at 700°C/300MPa: > 4000 h

Industrial or business partners in aeronautics are sought to commercialize this technology under a license agreement.
Advantages and Innovations:
This solution offers the following advantages compared to other conventional and traditional methods used:
- unmatched compromise resistance/ductility at high temperature
- Homogeneity of microstructures: with the ability of the process to retain microstructures
- Near net shape, which do not require post heat treatment
- Reproducibility of material
- Rapidity of manufacturing: compared to other traditional methods, less time is needed to reach peak temperature (minutes against hours)
- Cost reduction: savings of time and energy.

Stage of Development:
Under development/lab tested
IPs:
Patents granted
