  • Ultra-fine wire fabricating apparatus and method
    Patent number: 10245628
    Abstract: The ultra-fine wire fabricating apparatus comprises a feeder assembly, a stationary die, and a rotary die holder. The feeder assembly supplies a wire. The stationary die comprises a hollow inclined channel configured on an inner surface of the stationary die. The hollow inclined channel is configured to receive the wire from the feeder assembly. The rotary die holder configured to receive the wire from the stationary die and simultaneously torsionally deform the wire, wherein the rotary die holder rotates relative to the stationary die to produce the ultra-fine wire with improved mechanical properties. The method ensures continuous grain refinement of wires. The wires are severe plastic deformed using the combined effects of the stationary die and rotary die holder. The mechanical properties of the raw materials are improved due to a grain refinement and microstructure evolution caused by plastic deformation.
