abstract = {The highly flexible operation schemes of future thermal
energy conversion systems (concentrating solar power, heat
storage and backup plants, power-2-X technologies)
necessitate increased damage tolerance and durability of the
applied structural materials under cyclic loading.
Resistance to fatigue, especially thermomechanical fatigue
and the associated implications for material selection,
lifetime and its assessment, are issues not considered
adequately by the power engineering materials community yet.
This paper investigates the principal microstructural
evolution, damage and failure of two steels in
thermomechanical fatigue loading: Ferritic-martensitic grade
91 steel, a state of the art 9 wt $\%$ Cr power engineering
grade and the 22 wt $\%$ Cr, ferritic, stainless Crofer® 22
H (trade name of VDM Metals GmbH, Germany; under license of
Forschungszentrum Juelich GmbH) steel. While the
ferritic-martensitic grade 91 steel suffers pronounced
microstructural instability, the ferritic Crofer® 22 H
provides superior microstructural stability and offers
increased fatigue lifetime and more forgiving failure
characteristics, because of innovative stabilization by
(thermomechanically triggered) precipitation of fine Laves
phase particles. The potential for further development of
this mechanism of strengthening against fatigue is
addressed.},
