Production methods of metallic glasses by a suction casting method

Abstract

This invention provides a glassy metal-suction casting method capable of readily and conveniently producing a large-sized amorphous material with excellent properties as an amorphous material. Such an object of the invention is attained by filling a metal material in a mold cooled with water; melting said metal material by using a high-energy heat source which is capable of rapidly melting said metal material; and introducing the resulting molten metal instantaneously into a vertically extending water-cooled mold provided below said mold by using a difference in gas pressure or gravity to move the metal melt at a high speed and attain a high quenching rate to thereby enable the production of a glassy metal ingot of a large size.
