Room-Temperature Creep Of Lacoo3 -Based Perovskites: Equilibrium Strain Under Compression

Abstract

This study concerns an experimental investigation of room-temperature creep at different stresses in polycrystalline LaCoO3 -based oxides under compression. A phenomenological approach for ferroelastic creep is proposed to identify the most important parameters that affect creep strain over different time periods. An analytical expression is obtained instead of the previously used power law, allowing an estimation of equilibrium strain at constant stress. An expression is also proposed to calculate the characteristic time of creep and recovery processes. The equilibrium creep diagrams for LaCoO3 and La0.8 Ca0.2 CoO3 perovskites have been determined. © 2008 The American Physical Society.
