A technique for modifying the crystalline structure of a metallic microwire is introduced. The technique involves passing current through the wire via two electrical probes causing local Joule heating. We used this technique to heat a 25-μm-diameter Cu wire for 1 h at 573 K. The yield stress of the wire after modification was evaluated by a mechanical bending test and it was confirmed that the wire had softened after the process. We also performed heat treatment of a wire in a furnace and the properties of the wires modified by the two different methods were compared.
