Abstract

The present disclosure relates to aluminum-based products having 1-30 vol. % of a ceramic phase. The aluminum alloy products may be produced via additive manufacturing techniques to facilitate production of the aluminum-based products having the 1-30 vol. % of the ceramic phase.

First claim

What is claimed is:

1 . An aluminum alloy product, wherein the aluminum alloy product is a 2xxx or an 8xxx aluminum alloy, wherein the aluminum alloy product comprises one or more ceramic phases, and wherein the aluminum alloy product comprises 1-30 vol. % of the one or more ceramic phases, wherein the aluminum alloy product comprises a homogenous distribution of the at least one or more ceramic phases within the aluminum alloy product, and wherein the aluminum alloy product comprises a cellular structure having an average size of from 0.1 to 5 microns in the as built condition.

2 . The aluminum alloy product of claim 1 , wherein the aluminum alloy is a 2xxx aluminum alloy.

3 . The aluminum alloy product of claim 2 , wherein the one or more ceramic phases comprise TiB 2 .

4 . The aluminum alloy product of claim 3 , wherein the aluminum alloy is a 2519.

5 . The aluminum alloy product of claim 1 , wherein the aluminum alloy is an 8xxx aluminum alloy.

6 . The aluminum alloy product of claim 5 , wherein the one or more ceramic phases comprise TiB 2 .

7 . The aluminum alloy product of claim 6 , wherein the 8xxx aluminum alloy is 8009 or 8019.

8 . The aluminum alloy product of claim 1 , wherein a maximum size of any portion of the cellular structure is not great than 50 microns.

9 . A wrought aluminum alloy product, wherein the wrought aluminum alloy product is a 2xxx or 8xxx aluminum alloy, wherein the wrought aluminum alloy product comprises one or more ceramic phases, and wherein the wrought aluminum alloy product comprises 1-30 vol. % of the one or more ceramic phases, wherein the wrought aluminum alloy product comprises a homogenous distribution of the at least one or more ceramic phases within the wrought aluminum alloy.

10 . The wrought aluminum alloy product of claim 9 , wherein the aluminum alloy is a 2xxx aluminum alloy.

11 . The wrought aluminum alloy product of claim 10 , wherein the one or more ceramic phases comprise TiB 2 .

12 . The wrought aluminum alloy product of claim 11 , wherein the aluminum alloy is a 2519.

13 . The wrought aluminum alloy product of claim 9 , wherein the aluminum alloy is an 8xxx aluminum alloy.

14 . The wrought aluminum alloy product of claim 13 , wherein the one or more ceramic phases comprise TiB 2 .

15 . The wrought aluminum alloy product of claim 14 , wherein the 8xxx aluminum alloy is 8009 or 8019.

16 . A wire for use in electron beam or plasma arc additive manufacturing, the wire comprising:
an outer tube portion; and a volume of particles contained within the outer tube portion; wherein the outer tube portion is metallic aluminum or an aluminum alloy, and wherein the volume of particles contained within the outer tube portion are selected from the group consisting of ceramic particles, ceramic-metal particles, metal particles, and combinations thereof, wherein at least one of the ceramic particles and the ceramic-metal particles are present in the volume of particles.

17 . A method comprising:
using the wire of claim 16 with electronic beam or plasma arc additive manufacturing to produce an aluminum alloy product, wherein the aluminum alloy product comprises one or more ceramic phases, and wherein the aluminum alloy product comprises 1-30 vol. % of the one or more ceramic phases.
