      abstract     = {The 22 $wt.\%$ Cr, fully ferritic stainless steel
                      Crofer®22 H has higher thermomechanical fatigue (TMF)-
                      lifetime compared to advanced ferritic-martensitic P91,
                      which is assumed to be caused by different damage tolerance,
                      leading to differences in crack propagation and failure
                      mechanisms. To analyze this, instrumented cyclic indentation
                      tests (CITs) were used because the material’s cyclic
                      hardening potential—which strongly correlates with damage
                      tolerance, can be determined by analyzing the deformation
                      behavior in CITs. In the presented work, CITs were performed
                      for both materials at specimens loaded for different numbers
                      of TMF-cycles. These investigations show higher damage
                      tolerance for Crofer®22 H and demonstrate changes in damage
                      tolerance during TMF-loading for both materials, which
                      correlates with the cyclic deformation behavior observed in
                      TMF-tests. Furthermore, the results obtained at Crofer®22 H
                      indicate an increase of damage tolerance in the second half
                      of TMF-lifetime, which cannot be observed for P91. Moreover,
                      CITs were performed at Crofer®22 H in the vicinity of a
                      fatigue crack, enabling to locally analyze the damage
                      tolerance. These CITs show differences between crack edges
                      and the crack tip. Conclusively, the presented results
                      demonstrate that CITs can be utilized to analyze TMF-induced
                      changes in damage tolerance.},
