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.
