Process for producing amorphous alloy forming material

摘要

Disclosed is a process for producing an amorphous alloy forming material having at least 50% by volume of an amorphous phase which comprises the first-stage treatment in which an amorphous alloy is maintained in a temperature range below the glass transition temperature, the 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 improvesembrittlement peculiar to amorphous alloys subjected to thermal hysteresis for a long time and provides amorphous alloys excellent in strength, ductility and thermal plastic workability.
