Title
Real‐time in situ micro‐mechanical testing of hard metals using FIB‐SEM
Conference Dates
October 1-6, 2017
Abstract
The mechanical properties of WC/Co hardmetals were studied using in situ micro-mechanical characterisation techniques. Microscale pillars and cantilever beams were fabricated in different hardmetal microstructures using a focused ion beam microscope (FIB-SEM), to compare the behaviour between different orientation WC single crystals and polycrystalline structures. Micro-specimens in silicon were also tested to analyse the repeatability of the technique. The tests were done using a vacuum-compatible nanoindenter in a scanning electron microscope (SEM), which enabled simultaneous real-time observation of the test and acquisition of the load-displacement data.
