In our prior work, a T’-YSZ@Al<sub>2</sub>O<sub>3</sub> core-shell structure was developed to suppress ion diffusion between the T’-YSZ reinforcing phase and cubic yttria-stabilized hafnia (C-YSH) matrix, thereby stabilizing the phase structure and enhancing fracture toughness through ferroelastic toughening. Building on this foundation, we systematically investigated the influence of Al<sub>2</sub>O<sub>3</sub> shell thickness on ferroelastic domain switching by fabricating T’-YSZ@Al<sub>2</sub>O<sub>3</sub> ceramics with varying shell-to-core volume ratios (10 %, 20 %, 30 % Al<sub>2</sub>O<sub>3</sub>, denoted as CS10 %, CS20 %, CS30 %) via spark plasma sintering (SPS). Multiscale characterization (SEM, XRD, TEM, Raman) combined with FIB-assisted localized analysis and mechanical testing revealed that within a shell-core volume ratio range of 0–30 %, both hardness and elastic modulus increased monotonically with shell thickness. Notably, the fracture toughness peaked at 6.59 MPa·m<sup>1/2</sup> for CS20 % (shell-to-core ratio 0.2), representing an 18.5 % improvement over pure T’-YSZ. Beyond this threshold, excessive Al<sub>2</sub>O<sub>3</sub> compromised toughness by reducing the T’-YSZ reinforcement content. Furthermore, the Al<sub>2</sub>O<sub>3</sub> shell induced tensile stress within the T’-YSZ core, facilitating stress-driven ferroelastic domain switching. This interfacial stress engineering effectively enhanced domain switching and improving ferroelastic toughening efficiency.</div></div>","PeriodicalId":17408,"journal":{"name":"Journal of The European Ceramic Society","volume":"45 14","pages":"Article 117561"},"PeriodicalIF":5.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The as-deposited films exhibit reduced grain size, partial amorphization, and lack of ferro/piezoelectricity. Post-annealing led to a progressive enhancement of crystallinity and grain growth, restoring ferro/piezoelectric properties. Selected Area Diffraction (SAD) patterns of annealed samples confirm the coexistence of tetragonal and rhombohedral phases, characteristic of the morphotropic phase boundary (MPB). The 1000 °C annealed films exhibit the highest properties, with remnant polarization of ∼20 µC·cm<sup>−2</sup>, coercive field of 5 kV·mm<sup>−1</sup>, and maximum strain response of 0.3 % for a 10 KV·mm<sup>−1</sup> electric field. In addition, the annealing process reduces the leakage currents, indicating improved film quality. Energy harvesting tests using cantilever-based devices confirm effective mechanical-to-electrical energy conversion, with a maximum harvested power of 3.53 nW.

Herein, we discovered that the addition of SiCw can react in-situ with sintering additives, enabling SiC ceramics to achieve densification while incorporating a substantial quantity of whiskers. We systematically investigated the effects of stacking faults in SiC whiskers on the densification and microstructure of ceramics.
