      abstract     = {Advanced oxygen transport membrane designs rely upon a thin
                      functional layer supported by a porous substrate material
                      that carries the mechanical loads. The creep deformation
                      behavior needs to be assessed in order to warrant a
                      long-term reliable operation at elevated temperatures. The
                      current study reports the creep behavior of porous
                      La0.6Sr0.4Co0.2Fe0.8O3−δ in air for a temperature range
                      of 750–950 °C. Stress exponents and activation energies
                      are derived from the deformation data. A comparison with the
                      creep rates of dense material revealed a progressively
                      increasing creep rate with increasing temperature that might
                      be related to surface diffusional effects. Additional tests
                      at room temperature revealed non-linear stress–strain
                      curves and an apparent ferroelastic creep due to domain
                      switching in the rhombohedral phase that is stable at lower
                      temperature.},
