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.

Complex concentrated alloy and high entropy alloy additive manufacturing systems and methods

A method is provided for producing ultra-fine-grained materials using additive manufacturing. The method includes commanding, by a controller, a laser device to produce a plurality of optical pulses to a base material to add an additive material to the base material. The method further includes commanding, by the controller, a vibration mechanism to vibrate the base material as the plurality of optical pulses are being applied to the base material forming fine equiaxed grains with random crystallographic texture in the base material.

Producing ultra-fine-grained materials using additive manufacturing

A manufacturing process may comprise: stacking a plurality of friction discs together, each friction disc comprising a lug defining a surface; and depositing a composition to bond to the surface of a first friction disc in the plurality of friction discs to form a wear pad defining a wear surface.

Systems and methods for manufacturing wear pads

A vacuum arc remelt apparatus comprising a crucible having a wall, said wall having an interior and an exterior opposite said interior; an electrode within the crucible proximate the interior; an ingot within the crucible and below the electrode, wherein said ingot includes a crown and shelf; and a vibration source at the exterior of the crucible proximate the crown and shelf.
