Abstract

A composition includes an alloy that has, by weight, 25-65% zirconium, 25-65% tungsten, and 6-25% of a combined amount of nickel in at least one of iron and cobalt. The alloy may be formed into a geometric body that has a density of 7.8 grams per cubic centimeter to 11.4 grams per cubic centimeter.

First claim

What is claimed is:

1 . A composition of matter comprising:
an alloy including, by weight:
25-65% zirconium;
25-65% tungsten; and
6-25% of a combined amount of nickel and at least one of iron and cobalt.

2 . The composition as recited in claim 1 , wherein the alloy includes 5-20% nickel.

3 . The composition as recited in claim 1 , wherein the alloy includes 1-5% of at least one of iron and cobalt.

4 . The composition as recited in claim 1 , wherein the alloy includes iron and excludes cobalt.

5 . The composition as recited in claim 1 , wherein the alloy includes cobalt and excludes iron.

6 . The composition as recited in claim 1 , wherein the zirconium, tungsten, nickel, and at least one of iron and cobalt are distributed throughout the alloy.

7 . The composition as recited in claim 1 , wherein the alloy consists of:
25-65% zirconium; 25-65% tungsten; and 6-25% of a combined amount of nickel and at least one of iron and cobalt.

8 . The composition as recited in claim 1 , wherein the alloy consists essentially of:
25-65% zirconium; 25-65% tungsten; and 6-25% of a combined amount of nickel and at least one of iron and cobalt.

9 . An article comprising:
a geometric body formed of an alloy having a density of 7.8 grams per cubic centimeter to 11.4 grams per cubic centimeter, the density being selected with respect to a kinetic energy parameter of the geometric body, the alloy including zirconium, tungsten, nickel, and at least one of iron and cobalt.

10 . The article as recited in claim 9 , wherein the alloy, by weight, includes:
25-65% zirconium; 25-65% tungsten; and 6-25% of a combined amount of nickel and at least one of iron and cobalt.

11 . The article as recited in claim 9 , wherein the alloy includes 5-20% nickel.

12 . The article as recited in claim 9 , wherein the alloy includes 1-5% of at least one of iron and cobalt.

13 . The article as recited in claim 9 , wherein the alloy includes iron and excludes cobalt.

14 . The article as recited in claim 9 , wherein the alloy includes cobalt and excludes iron.

15 . The article as recited in claim 9 , wherein the zirconium, tungsten, nickel, and at least one of iron and cobalt are distributed throughout the alloy.

16 . The article as recited in claim 9 , wherein the alloy, by weight, consists of:
25-65% zirconium; 25-65% tungsten; and 6-25% of a combined amount of nickel and at least one of iron and cobalt.

17 . The article as recited in claim 9 , wherein the geometric body is spherical, cylindrical, or polygonal.

18 . An article comprising:
a reactive fragment formed of an alloy including, by weight:
25-65% zirconium;
25-65% tungsten; and
6-25% of a combined amount of nickel and at least one of iron and cobalt.

19 . The article as recited in claim 18 , wherein the alloy consists essentially of:
25-65% zirconium; 25-65% tungsten; and 6-25% of a combined amount of nickel and at least one of iron and cobalt.

20 . The article as recited in claim 18 , wherein the reactive fragment is spherical, cylindrical, or polygonal.
