Patent ID: RE44425

Claim:
A method for the continuous casting of sheets of an amorphous material comprising: providing a quantity of a bulk a solidifying amorphous alloy at a temperature above the melting temperature of the bulk solidifying amorphous alloy; stabilizing the bulk solidifying amorphous alloy at a casting temperature below the melting temperature (T m ) of the alloy and above the temperature at which crystallization occurs on the shortest time scale for the alloy (T NOSE ) such that the bulk solidifying amorphous alloy is in a viscosity regime of about 0.1 to 10,000 poise; introducing the stabilized bulk solidifying amorphous alloy onto a moving casting body such that a continuous sheet of heated bulk solidifying amorphous alloy is formed thereon; and quenching the heated bulk solidifying amorphous alloy at a quenching rate sufficiently fast such that the bulk solidifying amorphous alloy remains in a substantially amorphous phase to form a solid amorphous continuous sheet having a thickness of at least 0.1 mm.
