Development of new-generation ODS alloys and ODS composites

Anotace

The project deals with the development of new ODS alloys and ODS composites with the Fe-8-10wt%Al matrix. The alloys are prepared by mechanical alloying of Fe and Al powders in an oxidizing atmosphere, the composites by mechanical alloying of Fe, Al and Fe2O3 powders in an inert atmosphere. Then the mechanically alloyed powders are closed in the steel tube and consolidated by hot rolling. The stable microstructure is obtained by thermal or thermo-mechanical treatment. The resultant alloy or composite exhibit excellent oxidation- and creep-resistance at very high temperatures. The patent application was submitted recently.
