Webb22 nov. 2024 · Abstract: Magnetic shape memory alloy (MSMA) based actuators are extensively applied in the fields of precision manufacturing and micro/nano technology. Nevertheless, the inherent hysteresis in the MSMA-based actuator severely hinders its further application. WebbFabricating them with shape memory alloys (SMAs) expands the possibilities. The high strains experienced by auxetic structures may become reversible compared to ordinary metals due to superelastic or shape memory effect. ... Also, the occurrence of the hysteresis loop confirms the utilization of the stress-induced martensitic phase transition.
