Macroscopically phase separated melt-extracted wire. Continuous rapidly solidified wire shows Fe-Si-B amorphous core/Cu crystal cover layer structure [1].
We firstly develop a rapidly solidified Fe-Cu-Si-B alloy with a macroscopically separated structure by the arc-melt-type melt-extraction method [1]. A unique core-wire/surface-cover-layer structure composed of core Fe-Si-B-based amorphous alloy and cover Cu crystal was formed by liquid phase separation during rapid quenching of thermal melt.
