In-situ temperature‑controlled fatigue testing rig

The in-situ variable-temperature fatigue stage is a thermal‑mechanical testing platform specifically designed for material fatigue studies. When coupled with a scanning electron microscope, it enables real-time, in-situ observation of the evolution of a material’s microstructure under combined dynamic temperature and cyclic loading conditions.
