No notable stress is induced as there is not apparent phase transition on cooling when the ceramics are poled below orthorhombic‐tetragonal phase transition temperature (<italic>T</italic><sub>o–t</sub>). However, stress emerges by phase transition when poled above <italic>T</italic><sub>o–t</sub> leading to degrade <italic>d</italic><sub>33</sub>. Consequently, the ceramics poled near <italic>T</italic><sub>o–t</sub> exhibit the best <italic>d</italic><sub>33</sub> of 350 pC N<sup>−1</sup>.
