Cyclic Nanoindentation for Local High Cycle Fatigue Investigations: A Methodological Approach Accounting for Thermal Drift

Cyclic nanoindentation allows characterizing the influence of single phases and their interactions on fatigue mechanisms. Herein, a method for high cycle testing by is presented. By combining high- low-frequency indentation modes, numbers are achieved while obtaining sufficient data points to reconstruct force–displacement hysteresis loops. A challenge stochastic course thermal drift which addressed measuring rate in regular low-force holding segments. Drift rates used correct displacement values, yielding reproducible cyclic deformation as it shown two very different materials, ductile metal brittle ceramic.
