Methods of making bulk metallic glass from powder and foils

Abstract

Methods of forming a bulk metallic glass disclosed. The methods include packing a metallic glass-forming alloy powder to form a green body; heating the green body to a temperature between the glass transition temperature and the melting point of the metallic glass-forming alloy to form a heated green body; and cooling the heated green body to a temperature below the glass transition temperature of the metallic glass-forming alloy to form the bulk metallic glass. The methods of forming a bulk metallic glass also include packing one or more layers of an amorphous foil to form a green body; heating the green body to a temperature between the glass transition temperature and the melting point of the metallic glass-forming alloy to form a heated green body; and cooling the heated green body to a temperature below the glass transition temperature of the metallic glass-forming alloy to form the bulk metallic glass.
