A method and system of forming a micro-wire including heating metal feedstock to a liquid state within a glass tube, wherein the metal feedstock includes an iron based glass forming alloy comprising one or more of nickel and cobalt present in the range of 7 atomic percent to 50 atomic percent and one or more of boron, carbon, silicon, phosphorous and nitrogen present in the range of 1 to 35 atomic percent. Negative pressure may be provided to the interior the glass tube and the glass tube containing the metal feedstock may be drawn down. The metal feedstock in the glass tube may be cooled at a rate sufficient to form a wire exhibiting crystalline microstructures present in the range of 2 to 90 percent by volume in a glass matrix.
