Original abstract

Low cycle fatigue properties of oxide dispersion strengthened variant of the reduced activation ferritic-martensitic ODS Eurofer steel were determined. Due to a limited volume of the material prepared by powder metallurgy, small cylindrical specimens designed for the IFMIF irradiation campaign were used. The reliability of results obtained on small specimens was verified on Eurofer 97 steel. The properties of both Eurofer variants are compared. The main improvements of the ODS variant consist of higher cyclic stress level and lower cyclic softening.

Czech abstract

V této práci byly studovány únavové vlastnosit oxidicky zpevněné feriticko-martenzitické oceli Eurofer. Z důvodu malého množství materiálu připraveného práškovou metalurgii, byla zvolena válcová geometrie vrozku o průměru 2 mm. Bylo ověřeno, že velikost vzorku nemá vliv na únavové vlastnosti materiálu. Byly porovnány obě varianty oceli Eurofer (Eurofer 97 a ODS Eurofer). Oxidická disperze způsobuje značný nárůst napětí a značně snižuje cyklické změkčení.
