Technology (BMWI) as part of the research activities in the
membrane project "OXYMEM". The authors would like to express
their gratitude to Dr. W. Meulenberg and Dr. S. Baumann for
preparing and supplying the disk-shaped LSCF specimens. In
addition, the invaluable support by XRD characterization
provided by Dr. W. Fischer is highly appreciated.},
abstract = {Phase composition and thermo-mechanical properties of
La0.58Sr0.4Co0.2Fe0.8O3-delta (LSCF) have been studied. The
LSCF perovskite material comprised two phases: rhombohedral
and cubic, with a ratio that showed to depend on both
cooling rate as well as atmosphere. The fracture stress of
LSCF was determined on the basis of ring-on-ring bending
tests between room temperature (RT) and 800 degrees C. Below
700 degrees C nonlinear load-displacement curves were
obtained, an effect that is attributed to the
ferro-elasticity of the rhombohedral phase. Both SEM and TEM
verify the existence of a domain structure in the
rhombohedral grains. The indentation fracture toughness
appears to be insensitive to temperature variations from RT
up to 350 degrees C. The importance of thermal history on
phase composition and the resulting thermo-mechanical
behavior is discussed. (C) 2009 Elsevier B.V. All rights
