Abstract

Mechanical hooks made of bulk-solidifying amorphous alloys, wherein the bulk-solidifying amorphous alloys provide ruggedness, durability, higher service loads, excellent resistance to chemical and environmental effects, and low-cost manufacturing are provided. In addition, methods of making such mechanical hooks from bulk-solidifying amorphous alloys are also disclosed.

First claim

What is claimed is:

1. An engagement member formed from a bulk-solidifying amorphous alloy having an elastic strain limit of about 1.2% or more, comprising:
a first portion formed from the bulk-solidifying amorphous alloy and having a first substantially circular cross section;
a second portion formed from the bulk-solidifying amorphous alloy and having a second substantially circular cross section; and
a third portion extending from an end of the first portion to an end of the second portion and having a substantially rectangular cross section, the third portion formed from the bulk-solidifying amorphous alloy.

2. The engagement member of claim 1 , wherein the bulk-solidifying amorphous alloy has a glass transition temperature of 550° C. or above.

3. The engagement member of claim 1 , wherein the bulk-solidifying amorphous alloy comprises a nickel-containing alloy.

4. The engagement member of claim 1 , wherein the bulk-solidifying amorphous alloy comprises a ferrous alloy.

5. The engagement member of claim 1 , wherein the bulk-solidifying amorphous alloy has a hardness of at least about 7.5 GPa.

6. The engagement member of claim 1 , wherein the engagement member comprises an end with a sharpened tip.

7. A unitary hook-shaped member comprising a bulk-solidifying amorphous alloy having an elastic strain limit of about 1.2% or more, comprising:
a first section formed from the bulk-solidifying amorphous alloy and having a first substantially circular cross section;
a second section formed from the bulk-solidifying amorphous alloy and having a second substantially circular cross section; and
a curved section formed from the bulk-solidifying amorphous alloy and extending from an end of the first section to an end of the second section, the curved section having a substantially rectangular cross section configured to resist bending of the second section with respect to the first section.

8. The hook-shaped member of claim 7 , further comprising an end with a sharpened tip.

9. The hook-shaped member of claim 7 , wherein the bulk-solidifying amorphous alloy has a glass transition temperature of 500° C. or above.

10. The engagement member of claim 1 , further having a yield strength of 500 ksi or higher.

11. The hook-shaped member of claim 7 ,
wherein a cross-sectional area of the substantially rectangular cross section is larger than a cross-sectional area of the first substantially circular cross section.

12. The hook-shaped member of claim 7 ,
wherein the substantially rectangular cross section defines a long side and a short side; and
the long side is substantially parallel to a bending plane formed by the first section and the second section.

13. The hook-shaped member of claim 11 , wherein:
the substantially rectangular cross section defines a long side and a short side; and
the long side is substantially parallel to a bending plane formed by the first section and the second section.

14. An engagement member formed from a unitary bulk-solidifying amorphous alloy structure, comprising:
a first substantially straight portion having a first substantially circular cross section;
a curved portion joining the first substantially straight portion at a first end of the curved portion and having a substantially rectangular cross section; and
a second substantially straight portion joining the curved portion at a second end of the curved portion and having a second substantially circular cross section.

15. The engagement member of claim 14 , wherein a cross-sectional area of the second substantially straight portion is smaller than a cross-sectional area of the curved portion.

16. The engagement member of claim 15 , wherein a cross-sectional area of the first substantially straight portion is smaller than the cross-sectional area of the second substantially straight portion and larger than the cross-sectional area of the curved portion.

17. The engagement member of claim 14 , wherein a cross-sectional area of the curved portion is more than two times greater than a cross-sectional area of the first substantially straight portion.

18. The engagement member of claim 14 , wherein the bulk-solidifying amorphous alloy has a hardness of at least about 7.5 GPa.

19. The engagement member of claim 14 , wherein:
the second substantially straight portion defines a tip of the engagement member; and
the second substantially circular cross section tapers to a point at the tip of the engagement member.

20. The engagement member of claim 1 , wherein:
the end of the second portion is a first end;
the second portion further comprises a second end defining a tip of the engagement member; and
the second portion tapers from a first diameter at the first end to a second diameter smaller than the first diameter at the second end.

21. The hook-shaped member of claim 7 , wherein a diameter of the second substantially circular cross section tapers to a point along a length of the second substantially circular cross section.
