                      (LPPS) MCrAlY (M = Ni, Co) bond coats, Amdry 386, Amdry 9954
                      and oxide dispersion strengthened (ODS) Amdry 9954 (named
                      Amdry 9954 + ODS) were investigated after annealing in three
                      atmospheres: Ar–O2, Ar–H2O, and Ar–H2–H2O.
                      Freestanding bond coats were investigated to avoid any
                      influence from the substrate. Miniaturized cylindrical
                      tensile specimens were produced by a special grinding
                      process and then tested in a thermomechanical analyzer (TMA)
                      within a temperature range of 900–950 °C. Grain size and
                      phase fraction of all bond coats were investigated by EBSD
                      before testing and no difference in microstructure was
                      revealed due to annealing in various atmospheres. The
                      influence of annealing in different atmospheres on the creep
                      strength was not very pronounced for the Co-based bond coats
                      Amdry 9954 and Amdry 9954 + ODS in the tested conditions.
                      The ODS bond coats revealed significantly higher creep
                      strength but a lower strain to failure than the ODS-free
                      Amdry 9954. The Ni-based bond coat Amdry 386 showed higher
                      creep strength than Amdry 9954 due to the higher fraction of
                      the β-NiAl phase. Additionally, its creep properties at 900
                      °C were much more affected by annealing in different
                      atmospheres. The bond coat Amdry 386 annealed in an Ar–H2O
                      atmosphere showed a significantly lower creep rate than the
                      bond coat annealed in Ar–O2 and Ar–H2–H2O
                      atmospheres.},
