Abstract: Systems of weldable wires, powder, and materials comprising an aluminum-magnesium-scandium alloy, and methods for additive manufacturing the alloy are described. The alloy can be utilized in additive manufacturing to additively manufacture at industrial scales. With post treatment, the additive manufactured alloys can have advantageous properties for aerospace applications.

Abstract: A system and method are disclosed for cold working an additively manufactured component including a platform, a deposition robot, and a roller assembly. The platform is configured to support a three-dimensional object. The deposition robot is configured to deposit successive material layers that, after deposition, form the three-dimensional object. The deposition robot includes an arm having a deposition end and a deposition head coupled to the deposition end of the arm. The deposition head is configured to deposit a new material later of the successive material layers. The roller assembly is disposed around the new material layer and configured to compress a lateral thickness of the new material layer after the new material layer has been deposited by the deposition robot.

Abstract: Porous films with straight pores oriented normal to the plane of the films are produced through solution processing techniques. The production takes advantage of inorganic-surfactant or inorganic-polymer co-assembly and a patterned substrate. The patterned substrate, which is also produced via solution phase self-assembly, forces vertical orientation in a hexagonal cylinder system with no practical limits in substrate size or type. This provides a route to vertically oriented inorganic pores with a pitch ranging from 3 nm to over 15 nm and pore sizes ranging from 2 nm to over 12 nm. The size is tuned by choice the choice of organic templating agents and the deposition conditions. The pores can be produced with or without a capping layer which can be used to seal the nanopores.
