摘要：

Mechanical properties of a porous substrate of 40 vol.% Ni-60 vol.%o yttria-stabilized zirconia (YSZ), a Ni-YSZ functional layer, and a YSZ electrolyte layer were measured in compression from 1000 to 1200 C. The anode-supported bilayer is brittle for temperatures <1100 degreesC, but exhibits plasticity for higher temperatures. The plasticity is controlled by the Ni phase. Therefore, steady-state creep may limit the operational stress-temperature range. Published by Elsevier Science B.V.
