000014072 520__ $$2eng$$aNi-Mn-Ga Ferromagnetic Shape Memory Alloy (F SMA) has advantages in obtaining high-frequency large cyclic deformation with the magnetic-field driven martensite reorientation. However, most existing high-frequency tests on FSMA were conducted only for short time periods (a few seconds) to avoid temperature rise. In this work, we study the material’s long-time (> 4 minutes) high-fiequency dynamic behaviour. Particularly, the mechanism for the temperature rise and its influence on the dynamic output strain under different ambient conditions (with stagnant air and various ambient air flows) are investigated.
