Understanding the deformation of nanocrystalline (NC) metals is crucial for their practical application. So far, the deformation mechanism of ultrafine NC metals with grain size below 15 nanometre has been predicted by simulations which need to be verified experimentally. Using different in situ transmission electron microscopy deformation approaches, this project aims to determine deformation mechanisms of ultrafine NC platinum (Pt) at atomic-scale and to clarify how the deformation behaviour affects mechanical properties. The expected outcomes will advance the knowledge base in ultrafine NC metals and will provide guidance for developing advanced metallic materials with high strength/ductility that are the backbone for developing flexible and bendable devices.
