Measurement of the Mechanical Properties of Surfaces by Indentation
National Physical Laboratory (NPL) will host a one-day seminar on 9 May 2006 on 'Measurement of the Mechanical Properties of Surfaces by Indentation' at its site in Teddington, Middlesex, England.
Indentation has been used for many years as a way of easily assessing the mechanical state of materials. However historical indentations have been limited to the assessment of the hardness of a material. Whilst this has provided essential information for many applications in tribology, quality control and materials evaluation, the technique has the potential for providing much more information on materials behaviour.
Over the last few years, there have been many developments in the instruments and procedures that are used for indentation. A major feature is the instrumentation of the indentation process to give load and displacement information during the indentation that can then be analysed to give information on the elastic, plastic and time dependent properties of materials. Other developments, featured in this seminar, have enabled indentation measurements to be carried out in the transmission electron microscope (TEM), over large areas so that maps of mechanical properties can be generated, and under extreme conditions of temperature and fluid immersion.
