      abstract     = {The influence of the partial cubic-to-hexagonal phase
                      transformation of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) on the
                      creep behaviour of this perovskite-type oxygen transport
                      membrane was investigated. Isothermal compressive creep
                      tests were carried out in air in the temperature range
                      750-950 degrees C. Arrhenius plots of the creep rate
                      revealed a significant hysteresis effect. During heating,
                      the creep rate changed slightly up to about 850 degrees C
                      and increased substantially above this temperature. Upon
                      cooling from 950 degrees C it decreased in a nearly linear
                      manner to temperature. Microstructural investigations
                      support the conclusion that the hysteresis is linked with
                      the growth and transformation kinetics of the hexagonal
                      polymorph at the boundaries of cubic grains of BSCF. (C)
