Fe–Mn–Si/6.5wt%Si–Fe Bilayer Ribbons Produced by Using the Melt-Spinning Technique

Recently, progress of the intelligent materials plays a big role in development of science and technology. We have ever tried to develop ferromagnetic shape-memory alloys to expand the application range of the common nonmagnetic shape-memory alloys, which are typical intelligent material. However the saturation magnetization and the shape-memory effect were in a relation of the trade-off, so we could not get a good result. In this study, we tried to develop ferromagnetic shape-memory alloys as a composite material by using the single-roll melt-spinning technique. They are bilayer ribbons, which have both shape-memory layer and magnetic layer.
