Abstract
Official abstract text for this publication.
An alloy for structural direct-writing additive manufacturing comprising a base element selected from the group consisting of aluminum (Al), nickel (Ni) and a combination thereof, and a rare earth element selected from the group consisting of cerium (Ce), lanthanide (La) and a combination thereof, and a eutectic intermetallic present in said alloy in an amount ranging from about 0.5 wt. % to 7.5 wt. %. The invention is also directed to a method of structural direct-write additive manufacturing using the above-described alloy, as well as 3D objects produced by the method. The invention is also directed to methods of producing the above-described alloy.
First claim
Opening claim text (preview).
What is claimed is: 1. A solid alloy composition comprising: (i) layers of an alloy comprising a base element selected from the group consisting of aluminum (Al), nickel (Ni) and a combination thereof, and a rare earth element selected from the group consisting of cerium (Ce), lanthanum (La), and combination thereof, and a eutectic intermetallic present within said alloy in an amount ranging from about 0.5 wt. % to 7.5 wt. %; and (ii) an interface functioning to weld the layers, wherein said interface contains said eutectic intermetallic in an amount greater than the amount of the eutectic intermetallic within the layers of the alloy. 2. The alloy of claim 1 , wherein said rare earth element is Ce, wherein said Ce is present in said alloy in an amount up to 8 wt. %. 3. The alloy of claim 1 , wherein said rare earth element is La, wherein said La is present in said alloy in an amount up to 10 weight percent %. 4. The alloy of claim 1 , wherein said alloy further comprises at least one additional alloying element selected from the group consisting of iron (Fe), silicon (Si) and magnesium (Mg). 5. The alloy of claim 4 , wherein Fe is present in said alloy in an amount up to 2 wt. %, Si is present in said alloy in an amount up to 2 wt. %, and Mg is present in said alloy in an amount up to 30 wt. %. 6. The alloy of claim 1 , wherein said alloy further comprises an additive selected from the group consisted of SiC, carbon nanotube (CNT), alumina and boron nitride. 7. The alloy of claim 6 , wherein said additive is present in said alloy in an amount up to 30 vol %. 8. The alloy of claim 1 , wherein said alloy is an Al—Ce alloy, with said Ce present in an amount of about 0.5 to 7 wt. % by weight of said alloy, and said eutectic intermetallic is Al 11 Ce 3 . 9. The alloy of claim 1 , wherein said alloy is an Al—La alloy, and said eutectic intermetallic is Al 11 La 3 .
