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 called metal fatigue, which ...

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 ...

(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 ...

Each winter, the familiar grey haze settles over Indian cities, and with it comes more than just a scratchy throat or watery eyes. Poor air quality today carries a dangerous mix of toxic heavy metals, ...

(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 ...
