Abstract

Provided in one embodiment is a method for producing a composition, comprising: heating a first material comprising an amorphous alloy to a first temperature; and contacting the first material with a second material comprising at least one fiber to form a composition comprising the first material and the second material; wherein the first temperature is higher than or equal to a glass transition temperature (T_g) of the amorphous alloy.

Claims

1. A method for producing a composition, comprising:

contacting a first material comprising an amorphous alloy at a first temperature with a second material comprising at least one fiber to form a composition comprising the first material and the second material,

wherein the first temperature is higher than or equal to the glass transition temperature (T_g) of the amorphous alloy.

2. The method of claim 1, wherein the first temperature is less than the crystallization temperature (T_x) of the amorphous alloy.

3. The method of claim 1, wherein the first temperature is greater than T_x, and the method further comprises:

cooling the first material at a first cooling rate sufficient to form at least some of the amorphous alloy in the first material.

4. The method of claim 1, wherein the contacting further comprises applying a pressure to the first material.

5. The method of claim 1, wherein the first temperature is lower than a melting temperature of the second material.

6. The method of claim 1, wherein the contacting results in substantially no chemical interaction between the first material and the second material.

7. The method of claim 1, further comprising heating the first material to the first temperature.

8. The method of claim 1, wherein the first material comprises zirconium, titanium, iron, copper, nickel, gold, platinum, palladium, aluminum, or combinations thereof.

9. The method of claim 1, wherein the at least one fiber comprises an amorphous alloy or the element carbon, silicon, boron, oxygen, or combinations thereof.

10. The method of claim 1, further comprising producing the first material comprising an amorphous alloy.

11. The method of claim 1, wherein the contacting involves at least one of a dip coating process, a melt spinning process, and a melt infiltration process.

12. The method of claim 1, wherein the contacting further comprises:

disposing a first layer comprising the first material over a second layer comprising the second material to form a layered structure comprising the composition, and

applying a pressure to the layered structure such that a mechanical bond is formed between a first portion of the first layer and a second portion of the second layer.

13. A composition comprising a first material disposed over a second material, wherein

at least a portion of the first material is in contact with the second material,

the first material comprises a first amorphous alloy, and

the second material comprises at least one fiber.

14. The composition of claim 13, wherein the at least one fiber comprises an amorphous alloy or the element carbon, silicon, boron, oxygen, or combinations thereof.

15. The composition of claim 13, wherein the second material comprises a woven material comprising at least a first fiber comprising an amorphous alloy and a second fiber comprising carbon fiber.

16. The composition of claim 13, wherein the second material comprises pores and at least some of the pores are infiltrated by the first material.

17. The composition of claim 13, wherein the composition has at least one property selected from a tensile strength of greater than about 4.5 GPa, a tensile stiffness of about 100-500 GPa, a density of about 1.8-3.0 g/cm³, and a Vickers hardness of about 400-700 Hv.

18. The composition of claim 13, wherein the composition is resistant to corrosion.

19. The composition of claim 13, wherein the composition comprises about 50-99 vol. % of the second material.

20. The composition of claim 13, wherein the composition comprises less then about 3 vol. % carbide.

21. A composition comprising,

a woven material comprising at least one first fiber comprising a first material and at least one second fiber comprising a second material, wherein

the first material comprises an amorphous alloy, and

the second material comprises element carbon, silicon, boron, oxygen, or combinations thereof.

22. A method of producing a composition, the method comprising,

weaving together at least one first fiber comprising a first material and at least one second fiber comprising a second material to form a woven material,

wherein

the first material comprises an amorphous alloy, and

the second material comprises element carbon, silicon, boron, oxygen, or combinations thereof.
