  • Casting of amorphous metallic parts by hot mold quenching
    Patent number: 6620264
    Abstract: A manufacturing process for casting amorphous metallic parts separates the filling and quenching steps of the casting process in time. The mold is heated to an elevated casting temperature at which the metallic alloy has high fluidity. The alloy fills the mold at the casting temperature, thereby enabling the alloy to effectively fill the spaces of the mold. The mold and the alloy are then quenched together, the quenching occurring before the onset of crystallization in the alloy. With this process, compared to conventional techniques, amorphous metallic parts with higher aspect ratios can be prepared.
