This project aims at developing the use of light FeAL intermetallic alloys in substitution to steels and nickel alloys in transportation and power generation industries. Recent works (mainly in Europe) have allowed to solve the traditional problems that have limited the use of these materials until now. Today a European reference alloy is produced at laboratory scale. In this project, industrial manufacturing routes (powder metallurgy, forging...) will be developed. Components will be manufactured then tested in actual conditions. This fabrication will also be evaluated in economical terms. The use of FeAl in substitution to steels and nickel alloys will allow to enhance the efficiency of engines and power generation systems, to reduce weight and thus limit fuel consumption and to improve direct operating costs. Environmental friendliness will be improved through the reduction of pollutant emissions, the reduction of vibrations and external perceived noise, the saving of resources in strategic materials such as nickel and chromium and the limitation of their use as they are now recognized as dangerous for health.
