Abstract Scope |
Due to the recent advance in materials science, the demand for lightweight and damage-tolerant materials has increased for applications such as energy and the aerospace industry. Natural structural materials like bone or nacre, which consist of brittle minerals and a small amount of polymer, have attracted significant interest due to their unique multi-scale architecture such as brick-and-mortar structure which results in the improvement in damage tolerance. Since polymeric mortars have limitations in service temperature and fracture strength, researchers have proposed metal-ceramic composites with nacre-like structure as a novel structural material. In this study, we show the fabrication of nacre-like lamellar structured CuAgTi alloy-alumina composites. Ice-templated ceramic scaffolds were fabricated by freeze-casting and infiltrated with CuAgTi liquid alloy without external pressure owing to the excellent wettability. By controlling infiltration temperature, we examined how processing conditions can affect the microstructure and mechanical properties. |
