Ceramic structures for enhanced shape memory and pseudoelastic effects |
| 摘要 |
Shape memory and pseudoelastic martensitic behavior is enabled by a structure in which there is provided a crystalline ceramic material that is capable of undergoing a reversible martensitic transformation and forming martensitic domains, during such martensitic transformation, that have an elongated domain length. The ceramic material is configured as a ceramic material structure including a structural feature that is smaller than the elongated domain length of the ceramic material. |

1. A mechanical structure comprising:
a crystalline ceramic material that transforms between an austenitic phase and a martensitic phase by an applied stimulus, the martensitic phase including martensitic domains, each martensitic domain having a domain length; and wherein the ceramic material is configured as a ceramic material structure having a ceramic material feature extent that is smaller than the martensitic domain length of the martensitic phase ceramic material. |
