Synthesis and characterization of highly elastic TiCu-based amorphous micro-wires

Abstract

A series of TiCu-based quaternary amorphous wires from a deep eutectic alloy composition were prepared by arc-melting and melt-extraction methods. Continuous amorphous wires with good white luster and smooth surface were obtained in Ti25Zr15 Cu60-xNix (x = 0, 5, 10, 15 mol%) alloys. The TiCu-based amorphous wires exhibit high tensile strength exceeding 1.3 GPa and high elastic limit of over 1.4%. Good combine of mechanical properties make them viable for use in many micro mechanical systems.
