Abstract:Analysis of the creep behaviour of ferroelastic LaCoO 3 and La 0.8 Ca 0.2 CoO 3 perovskites at room and elevated temperatures is presented. It was found that the creep behaviour of the two LaCoO 3 -based compositions was determined by ferroelastic and non-ferroelastic creep strain components. Both the ferroelastic and non-ferroelastic creep strain components showed a strong dependence on bending stress. The ferroelastic creep depends on the coercive stress in LaCoO 3 based perovskites, which in turn is a funct… Show more
