The proposed project focuses on two aspects of microsample testing to measure mechanical properties of hardmetals at the local scale: the effect of geometry on the repeatability of the tests and the characterisation of interfacial strength. In a previous exploratory study, microsamples of different geometries (beams, pillars) were machined using FIB and tested with different nanoindenter systems. The measured force-displacement information obtained demonstrated good repeatability, captured the effect of WC orientation for fracture and discriminated WC-WC interfaces with different relative orientation. This project is the second stage of what could be an ambitious programme aiming at the development of robust metrology for the mechanical characterisation of key microstructural features in hardmetals.
The overall cost of the project to project partners will be €60k, to be shared by the participants (minimum 4). The project is planned to start in the forthcoming months and will last 12 months.
The project is open for all companies to participate in. A full description of the project is enclosed, including a Consortium Agreement (Page 1-2) to sign and return if you wish to be included as a partner.
