abstract = {Porous substrates are a prerequisite for advanced oxygen
transport membranes. In particular, phase stability and
mechanical robustness are of concern for long term
performance and reliability. These aspects were investigated
for porous Ba0.5Sr0.5Co0.8Fe0.2O3−δ material using
annealing experiments along with microstructural
investigations, depth-sensitive micro-indentation and
ring-on-ring bi-axial bending tests. Annealing studies
revealed phase instabilities at elevated temperatures that
were also characterized by X-ray diffraction analysis.
Elastic modulus and fracture stress were strongly affected
by the porosity, whereas their temperature dependency agreed
with the behavior of dense material.},
