Mechanical properties and magnetic behavior of deformed metal glass wires

Abstract
Fe75B15Si10 and Co72.5B15Si12.5 glass wires, when cold‐drawn, exhibit high magnetic squareness and coercive forces ranging from 1.0 to 20 Oe. These wires, upon magnetic switching in a pickup coil, produce a sharp voltage pulse of ∼6 V/cm2 turn. The Young’s modulus E, ΔE effects, fracture strength σf, and ac coercive force Hac of these wires in as‐quenched and cold‐drawn states are presented.
