      abstract     = {The mechanical stability of porous Ba0.5Sr0.5Co0.8Fe0.2O3-d
                      (BSCF) material was investigated using depth-sensitive
                      microindentation and ring-on-ring biaxial bending tests. The
                      porous BSCF was characterized as potential substrate
                      material for the deposition of a dense membrane layer.
                      Indentation tests yielded values for hardness and fracture
                      toughness up to a temperature of 400 degrees C, while
                      bending tests permitted an assessment of elastic modulus and
                      fracture stress up to 800 degrees C. In addition the
                      fracture toughness was evaluated up to 800 degrees C
                      measuring in bending tests the fracture stress of
                      pre-indented specimens. The results proof that the
                      indentation-strength method can be applied for the
                      determination of the fracture toughness of this porous
                      material. In comparison to dense material the values of the
                      mechanical parameters were as expected lower but the
                      temperature dependences of elastic modulus, fracture
                      strength and toughness were similar to those reported for
                      dense BSCF. (C) 2011 Elsevier Ltd. All rights reserved.},
