Abstract
Official abstract text for this publication.
A complex concentrated alloy (CCA) and/or high entropy alloy (HEA) additive manufacturing nozzle can include a nozzle body defining at least four powder channels. Each powder channel can be configured to be connected to a powder supply of a plurality of powder supplies to receive a powder from the powder supply for ejecting the powder toward a build area to form an additively manufactured article having a CCA and/or an HEA.
First claim
Opening claim text (preview).
What is claimed is: 1. A complex concentrated alloy (CCA) and/or high entropy alloy (HEA) additive manufacturing nozzle, comprising: a nozzle body defining at least four powder channels, each powder channel configured to be connected to a powder supply of a plurality of powder supplies to receive a powder from the powder supply for ejecting the powder toward a build area to form an additively manufactured article having a CCA and/or an HEA, wherein each powder channel is configured to change in flow area along a powder flow direction from a powder supply opening, through the nozzle body, to an ejection opening. 2. The nozzle of claim 1 , wherein the at least four powder channels include up to eight total powder channels. 3. The nozzle of claim 1 , wherein the at least four powder channels include eight total powder channels. 4. The nozzle of claim 1 , further comprising an energy application channel defined through the nozzle body and configured to pass energy to the build area to allow energy application to the powder ejected toward or on the build area. 5. The nozzle of claim 4 , wherein the energy application channel is an optical channel for passing a laser. 6. The nozzle of claim 5 , wherein the energy application channel is surrounded by the powder channels. 7. The nozzle of claim 5 , wherein an axis of the powder channels intersect with an axis of the energy application channel such that powder that is ejected from the powder channels intersects with the laser. 8. The nozzle of claim 6 , wherein the powder channels are disposed evenly and symmetrically around the energy application channel.
