Abstract
A method of rapidly annealing an amorphous metal core consists of applying a magnetic field to the core, immersing the core in a hot liquid for a period of time, and then placing the core in a cooling fluid. The hot liquid is preferably a molten metal or molten metal alloy, such as molten tin or solder. The cooling fluid may be an organic liquid or liquefied gas. Rapid magnetic annealing provides advantages not only of less time and energy costs, but also yields an annealed core that is more ductile than those of the prior art. The greater ductility permits a wound core to be annealed by this method and then rewound into another core.
