Abstract

A product includes a ternary alloy consisting essentially of Sn 4 Li (4+x) Zn (8−x) , where x=0 to <8. A method includes forming a ternary alloy using a mechanical alloying process. The ternary alloy consists essentially of Sn 4 Li (4+x) Zn (8−x) , where x=0 to <8.

Claims (22)

1. A product, comprising:

a ternary alloy consisting essentially of Sn 4 Li (4+x) Zn (8−x) , where x=0 to <8.

2. The product as recited in claim 1 , wherein the ternary alloy is physically characterized by remaining substantially in a single face center cubic (FCC) phase upon heating to about 900° C.

3. The product as recited in claim 2 , wherein the ternary alloy is physically characterized by remaining substantially in the single FCC phase upon cooling from the about 900° C.

4. The product as recited in claim 1 , wherein the ternary alloy is non-stochiometric.

5. The product as recited in claim 1 , wherein the ternary alloy has physical characteristics of formation by a mechanical alloying process.

6. The product as recited in claim 5 , wherein the mechanical alloying process includes high energy ball milling.

7. The product as recited in claim 1 , comprising a body comprising sintered nanoparticles of the ternary alloy integrated therein.

8. The product as recited in claim 7 , wherein the body comprises carbon fibers.

9. The product as recited in claim 7 , wherein the body comprises a magnetic element, wherein the magnetic element is selected from the group consisting of: Fe, Co, Cr, and Ni.

10. The product as recited in claim 1 , wherein x=0 to <3.5.

11. The product as recited in claim 1 , wherein x=0 to <3.

12. The product as recited in claim 1 , wherein x=4 to <8.

13. The product as recited in claim 1 , wherein x=4.5 to <8.

14. A method for forming the product of claim 1 , the method comprising:

forming the ternary alloy consisting essentially of Sn 4 Li (4+x) Zn (8−x) , where x=0 to <8 using a mechanical alloying process.

15. The method as recited in claim 14 , wherein the mechanical alloying process includes high energy ball milling.

16. The method as recited in claim 14 , wherein forming the ternary alloy comprises changing a stochiometric composition in the ternary alloy.

17. The method as recited in claim 14 , wherein the ternary alloy is physically characterized by remaining substantially in a single face center cubic (FCC) phase upon heating to about 900° C.

18. The method as recited in claim 17 , wherein the ternary alloy is physically characterized by remaining substantially in the single FCC phase upon cooling from the about 900° C.

19. The method as recited in claim 14 , comprising sintering nanoparticles of the ternary alloy.

20. The method as recited in claim 19 , comprising forming a body comprising the sintered nanoparticles of the ternary alloy integrated therein.
