Even though gears are made of metal, small holes can sometimes form on their surfaces.Why would holes form in hard ...

A National Institute for Materials Science (NIMS) research team has identified the mechanism by which microscopic fatigue cracks grow in metals, solving a half-century-old mystery. The team found that ...

(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 ...

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 ...
