abstract = {New oxygen transport membrane materials based on
SrTi1-xFexO3-δ, synthesized through solid state reaction
and processed via tape casting were characterized with
respect to their mechanical behaviour via depth-sensitive
indentation and ring-on-ring flexural testing. The elastic
moduli obtained by indentation with 1 N load for
SrTi1-xFexO3-δ (x = 0.25, 0.35, 0.5) specimens were 147 ±
10 GPa, 123 ± 6 GPa and 158 ± 10 GPa, respectively.
Fracture stress was accessed by ring-on-ring testing
performed at 100 N/min and the obtained results were 92 ± 9
MPa, 117 ± 15 MPa, and 100 ± 15 MPa for SrTi0.75Fe0.25O3,
SrTi0.65Fe0.35O3, and SrTi0.5Fe0.5O3 respectively.
Ring-on-ring tests conducted at different loading rates gave
access to subcritical crack growth sensitivity and aided the
prediction of the materials’ lifetime through
stress-time-probability diagrams, where SrTi1-xFexO3-δ (x =
0.25, 0.35, 0.5) may resist for 1 year with a failure
probability of $0.1\%$ at least 15 MPa, 22 MPa, and 12 MPa
respectively.},
