A fast and uniform heat treatment of 25-μm-thick Cu microwires was realized with Joule heating. To control the thermal boundary conditions around a wire, a constant direct current was supplied to the wire under vacuum conditions using current probes with sufficient heat capacity, and a uniform temperature distribution was realized in the wire. The grain size of the wire increased with the time for which current was supplied, and reached saturation within 10 s.
