Open Innovation Portal

The 4M2020 Open Innovation Portal has been set up to assist the Micro and Nano Manufacturing Community to develop a pro-active, collaborative environment. The portal can be used to support the development of three types of collaboration. We invite you to submit information in the following categories for organisations that are: • Developing state-of-the art products and services and are providing their expertise to external organisations (Product and Services Offering) • Looking for specific expertise and capability from other organisations (Product and Services Sought) • Wishing to collaborate in new projects and are looking for potential partners (Partner Search)

We report a new experimental protocol for quantitative measurements of plasticity in confined metal thin films. Significant plastic flow within metal thin films can be affected in both confined shear and compression, demonstrated presently in Cu thin films. Sputtering was used to deposit polycrystalline Cu and CrN films sequentially onto Si substrates, forming specimen assemblies in which Cu films of various thicknesses were confined between Si and CrN. Cylindrical micro-pillars of CrN/Cu/Si were fabricated through focused ion beam milling, with the interfaces either normal to the axial direction or at a 45° inclination. Compression loading of the micro-pillars in the axial direction produced extensive plasticity within the thin Cu interlayers in both cases but with distinctly different responses. Significant mechanical size effects were observed in both cases, offering an opportunity for quantitative evaluation of materials' plastic response at small length scales under different deformation geometries.
