Description	Tenké vrstvy ferroelastických materiálů (NiTi, NiMnGa), vyvíjené pro své jedinečné termo-, magneto- mechanické funkční vlastnosti, jsou používány jako pohonné jednotky v lékařské technice, MEMS a jiných mikro-systémech. Problémem výzkumu v tomto oboru je nedostatek vhodných experimentálních metod k vyhodnocení mechanických vlastností nejen těchto ale i jiných tenkých polykrystalických vrstev. Ty jsou totiž díky rozměrovému efektu a mikrostruktuře (velikost zrn <1um a výrazná přednostní orientace zrn) často velmi odlišné od běžného „objemového“ materiálu a silně směrově závislé. V rámci navrhovaného projektu chceme modifikovat metodu modální ultrazvukové spektroskopie, vyvinutou v naší laboratoři původně pro vyšetřování elastických vlastností monokrystalů slitin s tvarovou pamětí, ke studiu mechanických vlastností tenkých anisotropních vrstev. Vedle funkčních aplikací ferroelastických vrstev je znalost rovinných mechanických vlastností tenkých vrstev navíc nezbytná pro vyšetřování mechanické vazby mezi vrstvou a substrátem, což výrazně rozšiřuje použitelnost metody. V rámci řešení projektu se dále chceme zaměřit na studium souvislostí mezi funkčními mechanickými vlastnostmi a strukturními charakteristikami funkčních tenkých vrstev. Thin ferroelastic films are being developed for engineering applications in medical devices, MEMS and microrobotics systems. There seems to be a lack of reliable experimental methods for evaluation of mechanical properties of thin films. Due to the dimensional (thin films are nearly 2D objects) and microstructure (grain size <1um and strong texture) effects, these are frequently very different from the mechanical properties of the bulk materials (stronger and orientation dependent). The aim of this project is to develop a new Modal Resonant Ultrasound Spectroscopy /MRUS/ method for application to thin films. The MRUS method was originally developed in our laboratory for evaluation of temperature dependence of elastic constants of SMAs. The method will be particularly employed investigate the relationship between functional mechanical properties and structural characteristics of ferroelastic thin films in collaboration with leading European research centers where these films are being produced. Since knowledge of the planar mechanical properties of any thin films is essential for assessment of the mechanical coupling between the film and substrate, the applicability of the MRUS method for thin films thus extends much beyond the freestanding ferroelastic films.
