For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that ...

In the quest to optimize the efficiency of materials, attention is increasingly focused from the nanoscale to understanding how microscale defects, such as stacking faults and dislocations, affect the ...

This is a preview. Log in through your library . Abstract Experiments by transmission electron microscopy on thin foils of stainless steel have enabled the interaction of dislocations on different ...

Supersonic experiments are forcing physicists to rewrite a rule of thumb that has guided metal design for roughly 70 years, ...

A paper was recently published in Advanced Theory and Simulations by Pratik Dholabhai, Assistant Professor in the School of Physics and Astronomy at RIT. Professor Dholabhai obtained his M.S. in ...

When engineers want to make a metal stronger, one of the most reliable strategies is to use smaller grains—the microscopic ...

Engineers have spent decades trying to build metals that do not snap, melt, or grind away under extreme conditions, and for a ...

A metal is comprised of many individual crystals, or grains. These crystals are held together by electrons in the same way that electrons hold the atoms within each crystal together. For more on this ...
