Microstructures of coherent phase decomposition near morphotropic phase boundary in lead zirconate titanate
Click to view
(Color online) Computer simulation of coherent microstructures of phase decomposition in PZT near MPB. (a) Two-phase morphology at early-stage decomposition (simulation time ) and (b) coarsened morphology , where color scale shows the composition profile: tetragonal phase in red and rhombohedral phase in blue . (c) Close-up visualization of a portion of the phase-coexisting multidomain microstructure shown in (b), where arrows represent the in-plane components (, ) of polarization vector and the out-of-plane component is represented by color: red domains are tetragonal phase, green and blue domains are rhombohedral phase.
