What is claimed is: 1. A method for manufacturing an article, comprising: providing a metal box having an opening and a metal lid plate for closing the opening; placing a stack of alternating first metal and second metal layers inside the metal box, wherein a first metal in the first metal layers and a second metal in the second metal layers are operable to react under heat and pressure to form an intermetallic material; closing the opening with the metal lid plate to compress the stack inside the box to contact each inner metal wall of the box; and applying pressure and heat to the closed metal box to compress the stack and to cause reaction between two adjacent layers in the stack and reaction between the stack and each inner metal wall of the box to form metalurgical bonding between adjacent layers in the stack and between the stack and the metal box. 2. The method as in claim 1, wherein the first metal comprises titanium. 3. The method as in claim 1, wherein the second metal comprises aluminum. 4. The method as in claim 1, wherein the first metal comprises a titanium alloy. 5. The method as in claim 1, wherein the first metal comprise titanium and the second metal comprises aluminum. 6. The method as in claim 1, wherein the first metal comprises nickel. 7. The method as in claim 1, wherein the first metal comprises a nickel alloy. 8. The method as in claim 1, wherein the first metal comprises vanadium. 9. The method as in claim 1, wherein the first metal comprises a vanadium alloy. 10. The method as in claim 1, wherein the first metal comprises iron. 11. The method as in claim 1, wherein the first metal comprises an iron alloy. 12. The method as in claim 1, wherein the first metal comprises tantalum. 13. The method as in claim 1, wherein the first metal comprises a tantalum alloy. 14. The method as in claim 1, wherein the first metal comprises an aluminide-forming metal or alloy. 15. The method as in claim 1, wherein the second metal comprise an aluminum alloy. 16. The method as in claim 1, wherein the second metal comprise an aluminum metal matrix composite. 17. The method as in claim 1, wherein the second metal comprise an aluminum-infiltrate ceramic composite. 18. The method as in claim 1, wherein the first metal comprises a metal or alloy that forms intermetallic compounds with magnesium, including aluminum and its alloys. 19. The method as in claim 1, wherein the second metal comprises magnesium. 20. The method as in claim 1, wherein the second metal comprises a magnesium alloy. 21. The method as in claim 1, wherein the second metal comprise a magnesium metal matrix composite. 22. The method as in claim 1, wherein the second metal comprise a magnesium-infiltrate ceramic composite.
