The very recently developed coarse-grained new-generation oxide dispersion strengthened
(ODS) alloys containing 5 vol.% homogeneously distributed yttrium nano-precipitates seems to be
a promising oxidation-resistant structural material for applications at temperatures above 1000°C.
The primary aim of the present paper is the introduction of the new-generation oxide dispersion
strengthened (ODS) alloy and the first testing of its high temperature fatigue properties at 800°C,
concurrently demonstrating a novel and very efficient methodology by using an incremental fatigue
step test. The successful application of the methodology motivates the authors to test the fatigue
properties of new generation ODS alloys at 1000–1200°C in the near future.
