Binary Fe-based amorphous wires prepared by the melt-extraction method

Fe-based amorphous wires are promising in small-size functional components and devices due to their high thermal conductivity and soft magnetic properties. However, it is a great challenge to fabricate binary Fe-based amorphous wires through traditional preparation techniques. In this letter, Fe91Zr9 amorphous wires with a smooth surface and negligible deviation in diameter were firstly prepared using the melt-extraction method. Their microstructure, magnetic properties and tensile strength were evaluated. This work is expected to promote the application of Fe-based amorphous alloys in flexible sensors, wearables and magnetic refrigerants.
