Two-way shape memory effect of Ni<sub>50.1</sub>Mn<sub>24.1</sub>Ga<sub>20.3</sub> Fe<sub>5.5</sub> shape memory alloy polycrystalline fiber

Polycrystalline Ni-Mn-Ga-Fe fibers were prepared by melt-extraction technique. The internal stress and defects introduced by rapid solidification were modified by step-wise chemical ordering annealing. The microstructure and phase microstructure of fibers were characterized using Field Emission Scan...
