A Study on the Fabrication of Amorphous Magnetostrictive Wire

This paper is concerned with the fabrication of (Fe,Co)-Si-B amorphous magneto-strictive wire which attracts strong attention as a new sensor material. First, we put the ingot of (Fe$\sub$1-x/Co$\sub$x/)$\sub$77/Si$\sub$8/B$\sub$15/ composition into quartz tube. Then, under the condition of 400MHz and 8kW, we melt and mix the in-got in the high frequency induction furnance. After that, we obtain the magnetostrictive wire of 100∼150$\mu\textrm{m}$ in diameter by injection and rapid quenching within the high rotating water. Finally, we find that the wire is under the amorphous state.
