Abstract
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.
