2011 proved that high temperature nanoindentation continues to be a huge growth area in materials science. The operation and function of the NanoTest instrument from Micro Materials Ltd (MML) at temperatures up to 750°C is now well established and recognised, meaning that the challenge to the nanomechanical community is no longer in the acquisition of reliable data, but in the interpretation of the resulting data produced. 2011 saw the publication of some seminal papers in the area of high temperature nanoindentation. This article will offer a summary of selected work from users of the MML NanoTest system, which was the only instrument to produce publications featuring data above 200°C. This article will précis work carried out at temperatures above 600°C only.
