Strengthening Steel Without Sacrificing Ductility
2014-04-09 16:20:21

Brown University Researchers from Brown University and universities in China have found a simple technique that can strengthen steel without sacrificing ductility. The new technique, described in Nature Communications, could produce steel that performs better in a number of structural applications. Strength and ductility are both crucial material properties, especially in materials used in structural applications. Strength is a measure of how much force is required to cause a material...

Firing Temperature Determines Whether Glass Will Bend Or Break

Lee Rannals for redOrbit.com — Your Universe Online Researchers have found a way to determine whether glass will be brittle, or will have the ability to bend without breaking. The team wrote in the journal Nature Communications about how they've identified a temperature that allows you to determine whether you will be forming a brittle piece of glass, or ductile, which refers to a piece of glass' toughness. There is a temperature at which glass can become too viscous for...

Rice University researchers surprised to see twin-induced brittle-like fractures in gold nanowires Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale. A new study from Rice University finds gold wires less than 20 nanometers wide can become "brittle-like" under stress. It appears in the journal Advanced Functional Materials. The paper by Rice...

Materials scientists have known that a metal's strength (or weakness) is governed by dislocation interactions, a messy exchange of intersecting fault lines that move or ripple within metallic crystals. But what happens when metals are engineered at the nanoscale? Is there a way to make metals stronger and more ductile by manipulating their nanostructures? Brown University scientists may have figured out a way. In a paper published in Nature, Huajian Gao and researchers from the University of...

Researchers at the California Institute of Technology (Caltech) have developed a way to make some notoriously brittle materials ductile"”yet stronger than ever"”simply by reducing their size. The work, by Dongchan Jang, senior postdoctoral scholar, and Julia R. Greer, assistant professor of materials science and mechanics at Caltech, could eventually lead to the development of innovative, superstrong, yet light and damage-tolerant materials. These new materials could be used as...

By Ciulik, J It has been an exciting year in refractory metals. We had a very interesting symposium at the TMS 2008 Annual Meeting in New Orleans. Our "Refractory Metals 2009" symposium covered three areas: processing of refractory metals, characterization of refractory metals, and properties of refractory metals. Twenty-three presentations in three sessions made the symposium this year the largest and best attended we have had since I began attending refractory metals symposia (in 2002)....

Word of the Day
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
