Intermetallic metallic composite, method of manufacture thereof and articles comprising the same

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.

What is claimed is: 
     
         1 . 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.   
     
     
         2 . The method of  claim 1 , wherein the rolling in the roll mill is hot rolling. 
     
     
         3 . The method of  claim 2 , wherein the sheet further comprises a second layer of a third metal; the second layer being disposed upon the opposing faces of the sheet; wherein the third metal is chemically different from the first metal and the second metal. 
     
     
         4 . The method of  claim 1 , further comprising extruding the blank. 
     
     
         5 . The method of  claim 1 , further comprising winding the blank into a spool. 
     
     
         6 . The method 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. 
     
     
         7 . The method of  claim 1 , wherein the first metal is aluminum. 
     
     
         8 . The method of  claim 1 , wherein the first metal is magnesium. 
     
     
         9 . The method 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. 
     
     
         10 . The method of  claim 1 , wherein the second metal is aluminum. 
     
     
         11 . The method of  claim 1 , wherein the second metal is magnesium. 
     
     
         12 . The method of  claim 3 , wherein the third metal is nickel.
