摘要：
The present study reports on the mechanical behaviour of Br0.5Sr0.5Co0.8Fe0.2O3-delta under uniaxial compression at various temperatures. The stress-strain curve at room temperature shows a small but clear creep deformation, along with a hysteresis and a remnant strain, which could be related to a spin transition of cobalt. The hysteresis as well as Young's modulus decrease with increasing temperature to 473 K, at which temperature the creep behaviour disappears. The material shows conventional high-temperature creep above 673 K. (c) 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
