CONTINUOUS MANUFACTURING METHOD OF BULK AMORPHOUS ALLOY STRIPS TO PREVENT A NONUNIFORM STRUCTURE, AND BULK AMORPHOUS ALLOY STRIPS WITH A LOW MELTING POINT PRODUCED BY THE SAME

摘要

PURPOSE: A continuous manufacturing method of bulk amorphous alloy strips, and bulk amorphous alloy strips with a low melting point produced by the same are provided to continuously manufacture non-equilibrium phase alloy due to the bulk amorphous alloy strip having a low liquidous temperature and high glass forming ability.;CONSTITUTION: A continuous manufacturing method of bulk amorphous alloy strips(160) comprises the steps of: obtaining a vacuum degree of 10^-2 to 10^-1 Torr and an Ar gas purging atmosphere; melting quaternary mother alloy consisting of Cu, Zr, Ag, and Al in a crucible(110) of a twin-roll strip casting device(100); and supplying molten metal to the twin roll of the twin-roll strip casting device in the same atmosphere; and rapidly cooling and solidifying the molten metal.;COPYRIGHT KIPO 2013
