Method such as can be used, for example, for producing molded articles from metallic glasses. Method and apparatus are provided in which a good mold filling during casting is achieved in addition to high cooling rates. The method includes introducing a metal-containing melt into an electrically conducting casting mold, the metal-containing melt and the mold being connected in an electrically conducting manner to the outputs of the same voltage source during the introduction into a casting mold, so that a preset current flows through the boundary interface between the melt and the mold. Apparatus is also provided in which there is an electrically conducting connection to a voltage source between a metal-containing melt and an electrically conducting mold for the melt.

Process for producing metal-containing castings, and associated apparatus

A process by which solid magnet bodies can be efficiently produced from mrials with soft magnetic properties using the die casting process is disclosed. The process is characterized in that an alloy comprising the alloy constituents of the soft magnetic material in addition to one or more elements lowering the melting point is used as a starting material, and in that the additional elements are at least partially extracted from the magnet bodies that are produced from this alloy by the die casting method subsequently by a heat treatment in a reactive atmosphere. The process is applicable for the production of soft magnetic magnet bodies for relays, transformers, magnet valves, actuators, and other electromagnetic products.
