    摘要: An apparatus and method for casting metal strip includes a moving chill body that has a quench surface. A nozzle mechanism deposits a stream of molten metal on a quenching region of the quench surface to form the strip. The nozzle mechanism has an exit portion with a nozzle orifice. A depletion mechanism includes a plurality of independently controllable gas nozzles to supply a reducing gas to multiple zones of a depletion region located adjacent to and upstream from the quenching region. The gas flow profile can be controlled in each zone independently of controlling the gas flow in other zones. The reducing gas reacts exothermically to lower the density to provide a low density reducing atmosphere within the depletion and substantially prevent formation of gas pockets in the strip.

    摘要: A quench substrate for rapid solidification of molten alloy into strip has a microcrystalline or amorphous structure. The substrate is composed of a thermally conducting alloy and the structure is substantially homogeneous. The substrate is a thermal conducting material such as copper or a copper alloy, and has a constituent grain size uniformity greater than 1 .mu.m and less than 1,000 .mu.m in size.

    摘要: The invention provides an apparatus and method for continuously casting a filament, such as a glassy metal filament, at high speed within a zone of preselected vacuum. A continuous extrusion mechanism and a rapidly moving quench surface are located within a casting module. A vacuum mechanism provides the preselected vacuum in the module as the filament is cast, and a transport mechanism continuously moves the resultant rapidly advancing filament across the boundary between the vacuum in the casting airlock mechanism substantially preserves the module vacuum as the cast filament is transported across the boundary and a passivator mechanism passivates the quench surface to prevent the filament from adhering thereto.
