Michael Winterrose and Brent Fultz Use High-Pressure "Alchemy" to Create Nonexpanding Metals
07-01-09
Graduate student Michael Winterrose, and Brent Fultz, professor of materials science and applied physics, and colleagues, describe the exotic behavior of materials existing at high pressures in a paper in the June 12th issue of Physical Review Letters. By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, the material does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition. This insight into the behavior of materials existing at high pressures becomes doubly interesting when you consider that some 90 percent of the matter in our solar system exists at these high pressures.
