Abstract
A method of rapidly annealing an amorphous alloy consisting of applying a magnetic field to the alloy, immersing the alloy in a liquid comprising molten tin and then placing the amorphous alloy in a cooling fluid. 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 alloy that is more ductile than those of the prior art. The greater ductility permits the amorphous alloy to be annealed by this method and then rewound into a core.
