Anomalies in the thermomechanical behavior of Ba0.5Sr0.5Co0.8e0.2O3sigma ceramic oxygen conductive membranes at intermediate temperatures
Anomalies in the thermomechanical behavior of Ba0.5Sr0.5Co0.8e0.2O3sigma ceramic oxygen conductive membranes at intermediate temperatures
The thermomechanical properties of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) were measured using ring-on-ring tests and depth-sensitive microindentation. The cubic BSCF material exhibits an anomaly in mechanical properties between 200 and 400 degrees C. The observed anomaly is attributed to the transition...

The thermomechanical properties of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) were measured using ring-on-ring tests and depth-sensitive microindentation. The cubic BSCF material exhibits an anomaly in mechanical properties between 200 and 400 degrees C. The observed anomaly is attributed to the transition of Co3+ spin states which is experimentally confirmed by susceptibility measurements. Furthermore, slip lines were observed around the impression when indentation tests were carried out above 260 degrees C. |
