Structural, physical and damping properties of melt-spun Ni–Mn–Ga wire-epoxy composites

Ni–Mn–Ga is a ferromagnetic shape memory alloy that exhibits large, magnetic-field- and stress-induced strains via energy dissipating twinning when processed into single crystals. Grain boundaries suppress twinning and render polycrystalline Ni–Mn–Ga brittle. Ni–Mn–Ga/polymer composites overcome the drawbacks of polycrystals and could thus provide a less expensive and easier to handle alternative to Ni–Mn–Ga single crystals for damping...
