of crack tips became predominantly without the 90° domain switching, which led to the crack growth. Key words: ferroelectric ceramics; domain switching; in-situ Raman spectroscopy; Vickers...(Zr0.53Ti0.47)O3 (PLZT) polycrystalline ceramics with home-made experimental apparatuses. By assuming that ferroelectric ceramics are homogeneous and thus domain switching takes place only around the small......
