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.}, cin = {IEK-2 / IEK-1}, ddc = {670}, cid = {I:(DE-Juel1)IEK-2-20101013 / I:(DE-Juel1)IEK-1-20101013}, pnm = {122 - Power Plants (POF2-122)}, pid = {G:(DE-HGF)POF2-122}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000333488100126}, doi = {10.1016/j.ceramint.2013.12.085}, url = {https://juser.fz-juelich.de/record/153213}, }
