Melt Extracted Microwires

Amorphous microwires as a new category of advanced materials possess many excellent mechanical and magnetic properties, and have received considerable attention from both the research and industry community. Significant efforts have been devoted to the optimization of fabrication process, tailoring of mechanical and magnetic properties, sensor and microwave applications. To now, amorphous wires can be prepared by several methods such as glass coating (Taylor-wire technique), in-water quenching, and melt extraction technology (MET). Compared with others, the solidification rate of wires prepared by melt extraction is the highest, which endows the resultant wires many excellent mechanical and magnetic properties. To our best recollection, there is no dedicated monograph on melt extraction microwires yet. Therefore, in this chapter, we will focus on the melt-extracted amorphous microwires, detailing the fabrication process, wire formation mechanism, mechanical and magnetic properties, thus provide some technical base for its applications in sensor and multifunctional composites.
