Unbreakable Cell Phone Covers Likely To Hit The Markets Soon!
Research leader Carl. V. Thompson, the Stavros Salapatas Professor of Materials Science and Engineering and director of the Materials Processing Center at MIT, says that the team's study describes a way to systematically find the promising mixes from among dozens of candidates.
Writing about their work in the journal Science, the researchers describe glasses as solids whose structure is essentially that of a liquid, with atoms arranged randomly instead of in the ordered patterns of a crystal.
Glasses are generally produced by quickly cooling a material from a molten state in a process called quenching, according to background information in the research article.
"It is very difficult to make glasses from metals compared to any other class of materials, such as semiconductors, ceramics and polymers," Thompson said.
The researcher said that scientists have for decades focused on "understanding and on exploiting the remarkable properties of these materials, and on understanding why some alloy compositions can be made into glasses and others cannot."
However, according to Thompson, none of the scientists have been able to solve those mysteries to date.
He said that the new study did "provide a very specific and quantitative new insight into the characteristics of liquid alloys that can most readily be quenched into the glassy state," and thus provided a much more rapid way of discovering new alloys with the right properties.
