Design of Ferromagnetic Shape Memory Alloy Composites [PDF]

Journal of Composite Materials, 2004
Ferromagnetic shape memory alloy (FSMA) composites composed of a ferromagnetic material and a shape memory alloy (SMA) are key material systems for fast-responsive and compact actuators. The function of ferromagnetic material is to induce magnetic force which is then used to induce the stress in the SMA, resulting in the stress-induced marten site ...

Investigation of magnetic field-induced phase transition in Ni50Mn28Ga22, a ferromagnetic shape memory alloy [PDF]

AIP Advances
Ferromagnetic shape memory alloys (FSMAs) exhibit magnetic-field-induced strain (MFIS) through a reversible martensitic transformation. Among these, Nickel–Manganese–Gallium (Ni–Mn-Ga) alloys have drawn significant attention due to their large MFIS (up ...
