Abstract
Alloy materials and three-dimensional (3-D) printed alloys are disclosed. An alloy in accordance with an aspect of the present disclosure comprises aluminum, magnesium, and silicon wherein a composition of the alloy comprises from at least 5 percent (%) by weight to 20% by weight of silicon and from at least 7% by weight to 10% by weight of magnesium.
Claims (23)
1. An alloy, comprising:
aluminum (Al);
silicon (Si); and
magnesium (Mg), wherein the alloy has a Si/Mg ratio greater than 0.13 and wherein a composition of the alloy comprises less than or equal to 20% by weight of Si and less than or equal to 10% by weight of Mg, such that the alloy is a eutectic or near eutectic alloy.
2. The alloy of claim 1 , the alloy consisting essentially of Al, Si, and Mg.
3. The alloy of claim 1 , wherein a yield strength of the alloy is at least 450 Megapascals (MPa).
4. The alloy of claim 1 , wherein an elongation of the alloy is at least 4%.
5. The alloy of claim 1 , wherein a material hardness of the alloy is at least 80 on a Rockwell hardness (HRB) scale.
6. The alloy of claim 1 , further comprising at least one of silver, nickel, and manganese.
7. The alloy of claim 1 , further comprising calcium.
8. The alloy of claim 7 , wherein the alloy comprises between 0.1 and 0.45 percent by weight of calcium.
9. The alloy of claim 1 , further comprising zirconium.
10. The alloy of claim 9 , wherein the alloy comprises between 2 and 3.5 percent by weight of zirconium.
11. The alloy of claim 1 , further comprising calcium and zirconium.
12. The alloy of claim 11 , wherein the alloy comprises between 0.1 and 0.45 percent by weight of calcium and between 2 and 3.5 percent by weight of zirconium.
13. The alloy of claim 1 , wherein the alloy is produced by an additive manufacturing process.
14. The alloy of claim 13 , wherein the additive manufacturing process includes a cooling rate of at least 1000 degrees Celsius per second.
15. The alloy of claim 13 , wherein the additive manufacturing process includes at least one of Laser-Powder Bed Fusion, Electron Beam Powder Bed Fusion, or Directed Energy Deposition.
16. The alloy of claim 1 , wherein the alloy is a hyper-eutectic alloy.
17. The alloy of claim 1 , wherein the Mg is greater than or equal to 7% by weight and less than or equal to 10% by weight of the alloy.
18. The alloy of claim 17 , wherein the Si is greater than or equal to 5% by weight and less than or equal to 20% by weight of the alloy.
19. The alloy of claim 1 , wherein the Mg is greater than 8% by weight and less than or equal to 10% by weight of the alloy.
20. The alloy of claim 19 , wherein the Si is greater than or equal to 5% by weight and less than or equal to 20% by weight of the alloy.
