• Resumen

  • Discusses the creation of an amorphous steel by Joseph Poon, professor of physics, and Gary J. Shiflet, professor of materials science, at the University of Virginia. The strength of conventional steel is limited by defects that inevitably pop up in the crystalline organization of its atoms. Joseph Poon and Gary Shiflet and their colleagues devised amorphous steel that lacks those defects because it has randomly arranged molecular bonds. Although scientists have created amorphous alloys in the past, Poon and his team reported in the May 2004 Journal of Materials Research a way to make amorphous steel in bulk. The metal can then be cast in molds or shaped in the same way plastic can. Separately, researchers at Oak Ridge National Laboratory also reported making amorphous steel in bulk.
