摘要

Stronger than steel or titanium - and just as tough - metallic glass is an ideal material for everything from cell-phone cases to aircraft parts. Now, researchers at the California Institute of Technology (Caltech) have developed a new technique that allows them to make metallic-glass parts utilizing the same inexpensive processes used to produce plastic parts. With this new method, they can heat a piece of metallic glass at a rate of a million degrees per second and then mould it into any shape in just a few milliseconds. The research, led by Professor William Johnson, is reported in the May 13 issue of the journal, Science. "We've taken the economics of plastic manufacturing and applied it to a metal with superior engineering properties," Johnson says. "We end up with inexpensive, high-performance, precision net-shape parts made in the same way plastic parts are made - but made of a metal that's 20 times stronger and stiffer than plastic." A net-shape part is a part that has acquired its final shape.
