- Abstract:
-
Nanoindentation is extensively used to quantify nano-scale mechanical behaviour. A widely-used assumption is that a well-defined, materialindependent relationship exists between the indentation depth and indenter contact area. Here we demonstrate that this assumption is violated by ionimplanted tungsten, where pileup around the indenter tip leads to substantial changes in contact area. Using high accuracy surface acoustic wave measurements of elastic modulus, we are able to correct for this e...

Access Document
Why is the content I wish to access not available via ORA?
Bibliographic data (the information relating to research outputs) and full-text items (e.g. articles, theses, reports, etc.) arrive in ORA from several different sources. Unfortunately we are not able to make available the full-text for every research output.
Please contact the ORA team (
) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
Content may be unavailable for the following four reasons
Alternative access to the full-text
You may be able to access the full-text directly from the publisher's website using the 'Publisher Copy' link in the 'Links & Downloads' box from a research output's ORA record page. This method may require an institutional or individual subscription to the journal/resource.
