Engineers have identified a fundamental deformation mechanism that can be leveraged to greatly enhance the fatigue properties of metals, opening the door to a new strategy for designing ...

Material Technologies Inc. has many of the hallmarks of a startup. The Los Angeles-based company has technology that it claims will revolutionize its industry in this case the critical process of ...

(Nanowerk News) A new study in the journal Nature ("History-independent cyclic response of nanotwinned metals") shows how metals can be patterned at the nanoscale to be more resistant to fatigue, the ...

(Santa Barbara, Calif.) -- Take a wire paperclip. Now, bend it back and forth in the same spot 15, maybe 20 times. Chances are the paperclip will have broken before you finish. This is due to what's ...

A typical microstructure (grain structure at the micron scale) of metallic material. (Courtesy: J Stinville) The tiniest defects in a metal can cause it to fail, but predicting when this so-called ...

Fatigue due to repetitive strain is the leading cause of failure in metal components and structures, but new research shows how crystalline structures called nanotwins can slow the accumulation of ...
