Precipitation Hardening in Ferroelectric Ceramics. [PDF]

Adv Mater, 2021
AbstractDomain wall motion in ferroics, similar to dislocation motion in metals, can be tuned by well‐concepted microstructural elements. In demanding high‐power applications of piezoelectric materials, the domain wall motion is considered as a lossy hysteretic mechanism that should be restricted.
