METHOD FOR INCREASING THE DIAMETER OF A BULK AMORPHOUS ALLOY TO OBTAIN A UNIFORM BULK AMORPHOUS ALLOY WITHOUT INTERFACES

摘要

PURPOSE: A method for increasing the diameter of a bulk amorphous alloy is provided to obtain a bulk amorphous alloy with an increase diameter through repetitive casting.;CONSTITUTION: A method for increasing the diameter of bulk amorphous alloy comprises the steps of: forming a hole in the center of the bottom of a mold, coupling a bulk amorphous alloy having a specific diameter into the hole, injecting molten metal between the mold and the bulk amorphous alloy and cooling the molten metal, coupling the cooled bulk amorphous alloy with an increase diameter to a mold having a larger inner diameter and a hole in the center of the bottom thereof, and injecting molten metal between the larger mold and the increased bulk amorphous alloy and cooling the molten metal.;COPYRIGHT KIPO 2012
