Description
  • Fe3Al - based iron aluminides are structural materials, which are of interest for low material cost, low density, and excellent oxidation and sulfidation resistance. However, this material has the disadvantages of low room-temperature ductility. It is possible to improve the ductility by suitable alloying and by proper tharmaland mechanical treatment. It is the main task of the presented poster to describe the procedure, which enhances the ductility (alloying by cerium and anneling at 800 or 700 oC after rolling at 1000 oC followed by quenching into oil). The formability of aluminide Fe28Al4Cr was measured too and compared with that of the chromium steel. This test limits the temperature which can be used for hot rolling. The ductility and hardnessof Fe3Al - based alloys with and without cerium additon was compared as well as the microstructure of both alloys (with and without Ce).
