Abstract
A metal component is disclosed. The metal component has a first dimension greater than 5 mm, and a second dimension greater than 5 mm. The metal component may include where the alloy includes titanium, aluminum, vanadium, carbon, nitrogen, and oxygen. The alloy may include zirconium, titanium, copper, nickel, and beryllium. The metal component is not die-cast, melt-spun, or forged. An ejector and a method for jetting the metal component is also disclosed.
Claims12
A metal component, comprising:
- an alloy consisting essentially of an amorphous microstructure wherein the alloy has an elastic deformation of 0.2% or greater;
- wherein:
- the metal component has a first dimension greater than 1.5 mm;
- and
- a second dimension greater than 1.5 mm;
- and
- a composition of the alloy changes through a bulk of the metal component while maintaining an amorphous microstructure throughout and
- wherein:
- the amorphous microstructure comprises a microstructure dimension of from about 0.01 mm to about 0.75 mm;
- and
- the metal component is formed by a plurality of droplets wherein each of the plurality of droplets has been cooled at a rate of from about 100,000° C./sec to about 200,000° C./sec.

A method for jetting a metal, comprising:
- introducing a first alloy into an ejector defining an inner cavity and an exit nozzle;
- heating the first alloy in the ejector to form a liquid;
- ejecting a liquid droplet of the first alloy from the exit nozzle;
- allowing the liquid droplet to cool at a rate of from about 100,000° C./sec to about 200,000° C./sec to form an amorphous microstructure comprising a microstructure dimension of from about 0.01 mm to about 0.75 mm;
- and
- ejecting liquid droplets in a plurality of layers until a metal component is formed, wherein the metal component has a first dimension greater than 1.5 mm, and the metal component has a second dimension greater than 1.5 mm.
