摘要:
A solidified amorphous alloy material is produced from a melt of its desired metal material. A melt feeding route is provided with a first-stage quenching zone. The melt is quenched to a predetermined temperature in the first-stage quenching zone. The thus-quenched melt is then introduced into a second-stage quenching and solidification zone, whereby the melt is cooled further and solidified into a solidified material having an amorphous phase.

摘要:
A process for producing an amorphous alloy forming material having at least 50% by volume of an amorphous phase which comprises a first-stage treatment in which an amorphous alloy is maintained in a temperature range below the glass transition temperature, a second-stage treatment in which the alloy is maintained in a temperature range in the supercooled liquid region for a prescribed period of time, and quenching of the alloy thus treated. The process improves the embrittlement peculiar to amorphous alloys subjected to thermal hysteresis for a long time and provides amorphous alloys having excellent strength, ductility and thermal plastic workability.
