Abstract Scope |
Interfaces present in multimaterial components such as bi- and multilayered thin film structures may fail prematurely since they have to bridge the disparate physical properties of the adjacent materials. Thus, said interfaces dictate the overall lifetime of such structures. It is therefore crucial to study their reliability and understand the occurring failure mechanisms in detail to improve novel material composites and materials combinations. In the present study the fracture behavior of model crystalline-amorphous interfaces (Cu thin films delaminating from bulk glass substrates and nanocrystalline Cu – amorphous CuZr multilayers) are studied with advanced characterization techniques to understand the origin of delamination behavior, interface adhesion, and fracture under cyclic loading studied at the meso-scale and at the nanoscale with in situ transmission electron microscopy. |
