Ferroelectric ceramics, such as BaTiO<sub>3</sub> (BTO), can also demonstrate the shape memory effect (SME) through a ferroelectric-paraelectric transformation. While grain size (GS) is known to significantly influence SME in shape memory alloys (SMAs), its role in shape memory ceramics (SMCs) remains unexplored. In this work, BTO ceramics with GS ranging from 49 μm to 0.54 μm were prepared via a two-step sintering method to investigate the GS effect on SME. Results reveal that decreasing GS significantly enhances the residual strain, with the maximum residual strain increasing by approximately 3 times from 0.05 % (coarse grains, 49 μm) to 0.15 % (fine grains, 0.54 μm). This improvement is attributed to the increased number of 90° domains in smaller GS BTO ceramics. Additionally, external stress applied during cooling leads to a linear increase in residual strain. This phenomenon is explained from an energy perspective. Stress raises the system's strain energy, which encourages the formation of more 90° domains and fewer 180° domains as BTO transitions to the tetragonal phase. This work provides critical insights into enhancing SME in ferroelectric ceramics by controlling GS and domain structure, offering a potential strategy to tailor SME in SMCs.</div></div>","PeriodicalId":17408,"journal":{"name":"Journal of The European Ceramic Society","volume":"46 9","pages":"Article 118229"},"PeriodicalIF":6.2,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146191588","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 resistance measurement can be conducted stably up to 1200 ℃ in an argon atmosphere and 825 ℃ in air with excellent resistance stability and repeatability.</div></div>","PeriodicalId":17408,"journal":{"name":"Journal of The European Ceramic Society","volume":"46 9","pages":"Article 118211"},"PeriodicalIF":6.2,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146191680","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}
