Abstract

According to some configurations of the present disclosure, an alloy may include a composition that includes magnesium (Mg) that is approximately 5 to 12% by weight of the composition; manganese (Mn) that is approximately 0.1 to 2% by weight of the composition; and silicon (Si) that is approximately 0.3 to 3% by weight of the composition; and aluminum (Al) that is a balance of the composition. In one configuration, the composition may further include one or more of iron (Fe), titanium (Ti), zirconium (Zr), chromium (Cr), and/or yttrium (Y).

First claim

What is claimed is:

zirconium (Zr) that is
between 0.5% and 2% by weight of the composition, or
between 2.5% and 5% by weight of the composition; and

aluminum (Al).

2. The alloy of claim 1 , wherein the composition includes:
the Mg that is 2% to 4% by weight of the composition.

3. The alloy of claim 1 , wherein the composition includes:
the Mn that is 0.3% or greater by weight of the composition.

4. The alloy of claim 1 , wherein the composition includes:
the Zr that is between 0.6% and 2% by weight of the composition.

5. The alloy of claim 1 , wherein the composition further includes:
Fe that is up to 1% by weight of the composition.

6. The alloy of claim 5 , wherein the composition includes up to 0.25% by weight of the Fe.

7. The alloy of claim 6 , wherein the composition includes at least 0.05% by weight of the Fe.

8. The alloy of claim 1 , wherein the composition further includes up to 0.6% by weight of Ti.

9. The alloy of claim 8 , wherein the composition includes at least 0.1% by weight of the Ti.

12. The alloy of claim 1 , wherein the composition further includes up to 5% by weight of Cr.

13. The alloy of claim 12 , wherein the composition includes at least 1% by weight of the Cr.

14. The alloy of claim 1 , wherein the composition further includes up to 4% by weight of Y.

15. The alloy of claim 14 , wherein the composition includes at least 0.1% by weight of the Y.

16. The alloy of claim 1 , wherein elongation of the composition as-printed is at least 8%.

17. The alloy of claim 1 , wherein elongation of the composition as-printed is at least 10%.

18. The alloy of claim 1 , wherein elongation of the composition as-printed is at least 11.3%.

19. The alloy of claim 1 , wherein the composition further includes:
Fe that is up to 0.5% by weight of the composition.

20. The alloy of claim 1 , wherein the composition includes greater than or equal to 6% by weight of the Mg.

21. The alloy of claim 1 , wherein the composition includes less than or equal to 6% by weight of the Mg.

22. The alloy of claim 1 , wherein the composition includes greater than or equal to 1.5% by weight of the Mn.

23. The alloy of claim 1 , wherein the composition includes greater than or equal to 0.6% by weight of the Zr.

24. The alloy of claim 1 , wherein the composition includes greater than or equal to 0.8% by weight of the Zr.

25. The alloy of claim 1 , wherein the composition includes greater than or equal to 1.0% by weight of the Zr.

26. The alloy of claim 1 , wherein the composition includes greater than or equal to 2.6% by weight of the Zr.

27. The alloy of claim 1 , wherein the composition includes greater than or equal to 2.7% by weight of the Zr.

28. The alloy of claim 1 , wherein the composition includes greater than or equal to 2.8% by weight of the Zr.

29. The alloy of claim 1 , wherein the composition includes greater than or equal to 2.9% by weight of the Zr.

30. The alloy of claim 1 , wherein the composition further includes:
Cr that is up to 1% by weight of the composition.
