1. A method of making an alloy, comprising: positioning a first bulk-solidifying amorphous alloy having a dimension that is less than or equal to its critical dimension in contact with a second bulk-solidifying amorphous alloy different from the first bulk-solidifying amorphous alloy, thereby formin
1. A method of making an alloy, comprising: positioning a first bulk-solidifying amorphous alloy having a dimension that is less than or equal to its critical dimension in contact with a second bulk-solidifying amorphous alloy different from the first bulk-solidifying amorphous alloy, thereby forming a composite alloy preform;heating the composite alloy preform to a temperature greater than the glass transition temperature and lower than the melting temperature of at least the first bulk-solidifying amorphous alloy to form an alloy; andcooling the alloy. 2. The method of claim 1, further comprising subjecting the composite alloy preform to pressure while heating. 3. The method of claim 1, wherein heating is carried out at a temperature of from about 100° C. to about 1,600° C. 4. The method of claim 1, wherein heating is carried out at a temperature of from about 100° C. to about 750° C. 5. The method of claim 1, wherein at least one component of the second bulk-solidifying amorphous alloy is selected from the group consisting of metals or alloys of aluminum, bismuth, cobalt, copper, gallium, gold, indium, iron, lead, magnesium, mercury, nickel, potassium, plutonium, rare earth alloys, rhodium, silver, titanium, tin, uranium, zinc, zirconium, and mixtures thereof. 6. The method as claimed in claim 1, wherein the first bulk-solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu, Fe)b(Be, Al, Si, B)c, wherein “a” is in the range of from 30 to 75, “b” is in the range of from 5 to 60, and “c” is in the range of from 0 to 50 in atomic percentages. 7. The method as claimed in claim 1, wherein the first bulk-solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu)b(Be)c, wherein “a” is in the range of from 40 to 75, “b” is in the range of from 5 to 50, and “c” is in the range of from 5 to 50 in atomic percentages. 8. The method as claimed in claim 1, wherein the first bulk solidifying amorphous alloy can sustain strains up to 1.5% or more without any permanent deformation or breakage. 9. A method of making a composite alloy, comprising: positioning a metal or a metal alloy around at least a portion of a bulk-solidifying amorphous alloy different from the metal or metal alloy and having a dimension that is less than or equal to a critical dimension of the bulk-solidifying amorphous alloy, thereby forming a core/shell composite alloy preform;heating the core/shell composite alloy preform to a temperature greater than the glass transition temperature and lower than the melting temperature of the bulk-solidifying amorphous alloy to form a core/shell composite alloy; andcooling the core/shell composite alloy to form a core/shell amorphous alloyed article having at least an amorphous core. 10.

The method of claim 9, wherein: the bulk-solidifying amorphous alloy is a first bulk-solidifying amorphous alloy; andthe at least one metal or metal alloy is a second bulk-solidifying amorphous alloy different from the first bulk-solidifying amorphous alloy. 13. The method of claim 9, wherein the at least one metal or alloy of the metal is selected from the group consisting of metals or alloys of aluminum, bismuth, cobalt, copper, gallium, gold, indium, iron, lead, magnesium, mercury, nickel, potassium, plutonium, rare earth alloys, rhodium, silver, titanium, tin, uranium, zinc, zirconium, and mixtures thereof. 14. The method as claimed in claim 9, wherein the bulk-solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu, Fe)b(Be, Al, Si, B)c, wherein “a” is in the range of from 30 to 75, “b” is in the range of from 5 to 60, and “c” is in the range of from 0 to 50 in atomic percentages. 15. The method as claimed in claim 9, wherein the bulk-solidifying amorphous alloy is described by the following molecular formula: (Zr, Ti)a(Ni, Cu)b(Be)c, wherein “a” is in the range of from 40 to 75, “b” is in the range of from 5 to 50, and “c” is in the range of from 5 to 50 in atomic percentages. 16. The method as claimed in claim 9, wherein the bulk-solidifying amorphous alloy can sustain strains up to 1.5% or more without any permanent deformation or breakage. 17. A method of making a composite alloy, comprising: positioning a first bulk-solidifying amorphous alloy within at least a portion of a second bulk-solidifying amorphous alloy different from the first bulk-solidifying amorphous alloy and having a dimension that is less than or equal to a critical dimension of the second bulk-solidifying amorphous alloy, thereby forming a core/shell composite alloy preform;heating the core/shell composite alloy preform to a temperature greater than the glass transition temperature and lower than the melting temperature of at least the first bulk-solidifying amorphous alloy to form a core/shell composite alloy; andcooling the core/shell composite alloy to form a core/shell amorphous alloyed article having at least an amorphous surface. 18.
