Elevated temperature nanomechanics of coatings for high-temperature applications: a review

In this new publication, Micro Materials Director of Materials Research Prof Ben Beake reviews the state-of-the-art in elevated temperature nanomechanics of coatings for high temperature energy applications. The paper looks at the key factors influencing high temperature measurements and identifies strategies to improve data accuracy. Applications were chosen to highlight their differing requirements in terms of…

Nanoindentation and nano-impact of Zircaloy nuclear fuel cladding

In the recent publication by Vikas Tomar and colleagues at Purdue University (link below), the NanoTest was used to perform nanoindentation and nano-scale impact experiments on hydride precipitates embedded in a zirconium alloy in order to obtain the stress-strain response at temperatures up to 300 C. Zirconium alloys are used for cladding of fuel rods…

New Micro-impact demonstration video

Our new Micro-impact demo video provides a practical introduction for those unfamiliar with the impact technique. Presented by applications engineer Adrian Harris, the demonstration shows failure of a DLC coating under the highly loaded repetitive contacts of a micro-impact test.

Using Nano-impact on layered MAX phase systems

Nano-impact is a unique tool for investigating the mechanical response and deformation characteristics of materials under high strain rates.In the article linked below, nano-impact was used by researchers at the University of Huddersfield on a Cr2AlC MAX phase to assess the mechanical response of the coating under dynamic loading conditions. No failure or localised fracture…

Micro Materials collaboration with GP Plasma and SIOMEC

Residual stresses in coated components can influence their performance. Micro Materials have been collaborating with GP Plasma and SIOMEC to study residual stress profiles in thin hard coatings. By performing a grid of indentations within a calotte crater with the NanoTest Vantage and analysing the results with the unique SIO software, it was possible to…
