Nano- and Micromechanical Lab

The nano- and micromechanical lab within the SMART-H project is dedicated to understanding the hydrogen-material reaction at a nano- to micro-scale. In-situ and ex-situ hydrogen-charging approaches are specially designed for small-scale mechanical testing. Instrumented nanoindentation and small-scale tensile tests are the most frequently used testing techniques. The combination of the small-scale mechanical testing and ex-situ/ in-situ hydrogen-charging can reveal a wide range of material’s intrinsic physical behavior when in reaction with hydrogen.
