Abstract

Disclosed herein is an article comprising a plurality of domains fused together; wherein the domains comprise a core comprising a first metal; and a first layer disposed upon the core; the first layer comprising a second metal; the first metal being chemically different the second metal. Disclosed herein too is a method comprising rolling a sheet in a roll mill; the sheet comprising a first metal and having disposed upon each opposing face of the sheet a first layer that comprises a second metal; the second metal being chemically different from the first metal; cutting the sheet into a plurality of sheets; stacking the plurality of sheets; and rolling the stacked sheets in the roll mill to form a blank.

First claim

What is claimed is:

1. An article comprising:
a plurality of domains fused together; wherein the domains comprise:
a core comprising a first metal; and
a first layer disposed upon the core; the first layer comprising a second metal; the first metal being chemically different the second metal; wherein the domains comprise a gradient in composition between the first metal and the second metal; wherein the core is in the form of a particle having a domain size of 44 to 1400 micrometers, and wherein the plurality of domains have interstices between them;
a second layer that is disposed upon the first layer, wherein the second layer comprises a third metal that is different from the first metal and the second metal; where the third metal is nickel, aluminum, magnesium zinc, copper, iron, cobalt, or a combination thereof; where the third metal is present in an amount of 0.01 to 0.1 wt %, based on a total weight of the article; where the second metal is present in an amount of 8 to 10 wt %, based on the total weight of the article.

2. The article of claim 1 , wherein the article is a supporting element in a sealable system for oil exploration.

3. The article of claim 1 , wherein the article is an actuating ball for a borehole system.

4. The article of claim 1 , wherein the first metal is aluminum, magnesium, zinc, copper, iron, nickel, cobalt, or a combination comprising at least one of the foregoing metals.

5. The article of claim 1 , wherein the first metal is aluminum.

6. The article of claim 1 , wherein the first metal is magnesium.

7. The article of claim 1 , wherein the second metal is aluminum, magnesium, zinc, copper, iron, nickel, cobalt, or a combination comprising at least one of the foregoing metals.

8. The article of claim 1 , wherein the second metal is aluminum.

9. The article of claim 1 , wherein the second metal is magnesium.

10. The article of claim 1 , wherein the article is manufactured by rolling a sheet comprising the first metal and coated on each of its opposing faces with a first layer comprising the second metal, cutting the rolled sheet into a plurality of sheets; stacking the plurality of sheets; re-rolling the stacked sheets in the roll mill; and repeatedly cutting, stacking and rolling the stacked sheets.

11. An article comprising:
a plurality of domains fused together; wherein the domains comprise:
an intermetallic fine grained alloy that comprises a first metal, a second metal and a third metal; wherein the domains comprise a gradient in composition between the first metal and the second metal; and wherein the first metal is chemically different the second metal; wherein a core of the domain comprises the first metal and is in the form of a particle having a domain size of 44 to 1400 micrometers, and wherein the plurality of domains have interstices between them; where the third metal is different from the first metal and the second metal; where the third metal is nickel, aluminum, magnesium zinc, copper, iron, cobalt, or a combination thereof; where the third metal is present in an amount of 0.01 to 0.1 wt %, based on a total weight of the article; where the second metal is present in an amount of 8 to 10 wt %, based on the total weight of the article.

12. The article of claim 11 , wherein the article is a supporting element in a sealable system for oil exploration.

13. The article of claim 11 , wherein the article is an actuating ball for a borehole system.

14. The article of claim 11 , wherein the first metal is aluminum.

15. The article of claim 11 , wherein the first metal is magnesium.

16. The article of claim 11 , wherein the second metal is aluminum.

17. The article of claim 11 , wherein the second metal is magnesium.
