Abstract
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.
