Abstract

Hard materials present significant metrological challenges in order to characterise, in particular, their mechanical properties. For example, when measuring hardness the indentations are small and difficult to measure accurately. In addition, deformation processes can be dimension and microstructure dependent, so the choice of indentation load requires significant underpinning research to ensure that the measured values are repeatable and reproducible. Often, surface mechanical measurements result in the development of small cracks. These also require characterisation and, with careful quantitative measurements, can reveal information on hard material toughness.
