21. A method of forming a stent, comprising:
-
providing a molten piece of bulk-solidifying amorphous alloy;
providing a mold in the shape of a desired stent component;
casting the molten amorphous alloy into a plurality of near-to-net shape stent components;
assembling a stent from the stent components; and
compacting the stent radially to form a compacted stent, wherein the amorphous alloy piece is subjected to an elastic strain of at least 1.0% during compacting. - View Dependent Claims (22, 23)

providing a feedstock a bulk-solidifying amorphous alloy;
heating the feedstock to around the glass transition temperature of the amorphous alloy;
providing a mold in the shape of a desired stent component;
molding the molten amorphous alloy into a plurality of near-to-net shape stent components;
assembling a stent from the stent components; and
compacting the stent radially to form a compacted stent, wherein the amorphous alloy piece is subjected to an elastic strain of at least 1.0% during compacting. - View Dependent Claims (25, 26)
