Abstract
A metallic glass-coated wire is formed by drawing a hollow glass fiber from a container in which molten alloy is entrained and solidified. Interference stresses extant between the glass coating and the alloy core of the wire are produced by systematically controlling thickness and mechanical elastic properties of the glass. The interference stress is tailored by selection of glass thickness and chemistry to optimize wire drawing process conditions, such as drawing temperature and strain rate. In addition, the interference stress is especially tailored to assure physical integrity of the glass-alloy composite wire product. Local property variations along the wire length are minimized, facilitating production of discrete wire segments especially suited for use in EAS applications.
