Abstract:
A method of joining a bulk-solidifying amorphous alloy material to a non-amorphous metal material wherein the melting temperature of the bulk-solidifying amorphous alloy material is higher than the melting temperature of the non-amorphous material, comprising:providing a pre-formed piece, wherein the pre-formed piece is made of the bulk-solidifying amorphous alloy material; casting a second piece at a casting temperature in a joining relationship with said pre-formed piece to form a single integral article, wherein the second piece is made of the non-amorphous metal material, and wherein the casting temperature is greater than the melting temperature of the non-amorphous metal material; and cooling the single integral article at a rate sufficient to ensure that the bulk-solidifying amorphous alloy material remains substantially amorphous.
