Low-cycle fatigue and shape-recovery performance of thermal-mechanically trained Fe-SMAs for seismic devices

Key Points

• Improved shape-recovery performance enhances functionality in seismic devices, particularly under stress conditions.
• Testing showed low-cycle fatigue resistance for thermal-mechanically trained Fe-SMAs, outperforming untreated alloys.
• Assessment of fatigue characteristics employed controlled mechanical experiments in laboratory settings.
• These findings support the adoption of Fe-SMAs in seismic applications, warranting further field trials.
