Instrumented Indentation is the future of hardness testing. It is able to measure both hardness and elastic modulus from the same indentation experiment. It is able to do anything conventional hardness testing can do but is also one of the only methods to be able to measure both elastic and plastic properties of small volumes of materials. For example, it can measure the elastic modulus of a sub micron thick coating with an uncertainty comparable to state-of-the-art uniaxial tensile testing of a steel bar. This guide aims to provide a rapid introduction to the technique and is structured to cater both for new users and those operating at higher levels of complexity and/or accuracy. Sections marked for “advanced users” contain the fine detail that may not be relevant for every user, being of most interest to those operating at high resolution and accuracy.
