Nuclear Materials

The nanoindenter records load and displacement changes in µN and sub-nanometre scales during indentation of a µm sized tip into a sample surface. Various methods, such as Continuous Measurement Stiffness, as well as different shapes and sizes of the indenter tips, can provide information on the mechanical properties of the material of interest.

Uses

The small volume required for the tests, as well as the automation of the device, makes it a great tool for gathering statistical data on mechanical properties of the surface of the materials. Hardness, elastic modulus, yield stress and true stress vs true strain behaviour can be obtained for bulk materials, and even for thin films.
