Anotace

Advanced micro/nanocrystalline (mc/nc) materials promise to become key building blocks in future technologies, where they must feature enhanced performance at extremes of stress, temperature or pressure. In this respect, innovative and multidisciplinary basic research should only elucidate fundamentally how materials behave under extreme conditions is required. The purpose is to advance the state-of-the-art of mc/nc materials by developing new metal-based structures through architectural control at appropriate microstructural scale and their characterization by complementary methods including positron annihilation spectroscopy, 3D electron/ion tomography and filtered electron microscopy. These techniques will be shared by all participants and combined with traditional techniques to produce breakthroughs needed for future applications. The objectives are severe plastic deformation of difficult-to-work alloys, powder metallurgy, hydrogen storage, in situ nanomechanical testing of small-scale systems, biodegradable alloys and grain boundary pinning by in situ nanoparticles.
