| | Invent by Number: Researchers predict, then produce superior titanium alloys: Science News Online, April 19, 2003 (Site not responding. Last check: 2007-09-02) |
 | | In recent years, some scientists have said that alloy development is a mature field with little room for improvement. |
 | | This week, however, researchers report a new method for making titanium-based alloys with many qualities far superior to those in any alloy previously known. |
 | | The researchers determined that a desirable titanium-based alloy must meet three criteria, which they call "magic numbers," that are based on quantum mechanical calculations reflecting the behavior and arrangement of atoms and electrons. |
