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...

Advances In Glass Alloys Lead To Strength, Flexibility
2014-03-04 12:36:16

DOE/Los Alamos National Laboratory What do some high-end golf clubs and your living room window have in common? The answer is glass, but in the golf clubs' case it's a specialized glass product, called metallic glass, with the ability to be bent considerably and spring back into its original form. Your windows, as you know, aren't quite as forgiving of a sudden impact, and they shatter – they are brittle, as opposed to ductile, or more flexible products. For the golf clubs, however, a...

When deciding what materials to use in building something, determining how those materials respond to stress and strain is often the first task. A material’s macroscopic, or bulk, properties in this area — whether it can spring back into shape, for example — is generally the product of what is happening on a microscopic scale. When stress causes a material’s constituent molecules to rearrange in a way such that they can't go back to their original positions, it is known as “plastic...

New research Shows 'Perfect Twin Boundaries' Are Not So Perfect
2013-05-20 10:55:02

University of Vermont One of the basic principles of nanotechnology is that when you make things extremely small–one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair–they are going to become more perfect. "Perfect in the sense that their arrangement of atoms in the real world will become more like an idealized model," says University of Vermont engineer Frederic Sansoz, "with smaller crystals–in for example, gold or...

Firing Temperature Determines Whether Glass Will Bend Or Break
2013-02-28 16:24:11

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...

When materials are stressed, they eventually change shape. Initially these changes are elastic, and reverse when the stress is relieved. When the material's strength is exceeded, the changes become permanent. This could result in the material breaking or shattering, but it could also re-shape the material, such as a hammer denting a piece of metal. Understanding this last group of changes is the focus of research from a team including Carnegie's Ho-kwang "Dave" Mao. Their breakthrough...

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...

Hohai University in Nanjing has established a research tradition in hydraulic engineering over the last 95 years. During this time, Hohai has become a first class institution of higher education that focuses on a wide range of engineering subjects including civil engineering and water resources, which are of particular interest. China's hydropower development occurs mainly in the high mountains and canyons of the Qinghai-Tibet plateau in the southwestern provinces. Because of long term...
