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.
Claims21
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.
An ejector for jetting a metal component, comprising:
- a structure defining an inner cavity to receive a first metal;
- a nozzle orifice in connection with the inner cavity and configured to eject one or more droplets of a liquid metal comprising the first metal;
- and
- wherein:
- the first metal is allowed to cool at a cooling rate to form an amorphous microstructure;
- and
- a first dimension of a formed metal component has a first dimension greater than 1.5 mm and a second dimension greater than 1.5 mm.
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 to form an amorphous microstructure;
- 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.
