Abstract

Based on the ferroelectric microstructural residual stress model, the relation between grain size and residual elastic energy was proposed. It was found that the residual elastic energy increased with decreasing grain size by modeling and DSC results. This residual elastic energy change with grain size which induce the phase transituion mode change was the cause of a diffuse phase transition in small grain size.
