Ferroelectric and piezoelectric polycrystalline ceramics exhibiting large electromechanical response are sought after in electronic devices such as actuators, transducers in sonar, sensors, accelerators, aerospace, ...

We have studied spinodal decomposition which leads to a three-phase microstructure in ternary alloys using computer simulations based on the ternary Cahn-Hilliard equations. All the alloys we have studied are in the same ...
