One million indents, a hardness (and modulus) story

Conference Dates

September 29-October 4, 2019


Advances in nanomechanical testing have progressed to a point where high-speed mapping and large data sets have become achievable. An Edisonian approach to indentation spacing and rate determines the experimental parameters that are then applied to a modern Damascene steel. One million indents were then performed over a period of less than 6 days thereby mapping out an area of 1mm x 1mm with a spacing of 1µm. To make sense of the data, artificial intelligence algorithms are used to provide an analysis of the hardness and modulus data.
