The disorder in the molecular array of a crystal lattice caused by a fission fragment has been studied by high-resolution electron microscopy. Disturbances in the (201) fringes of platinum ...

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 ...

For a Ti alloy single crystal, the stress required for deformation twinning increases dramatically as the size of the crystal decreases, until at submicrometre sizes, deformation occurs solely by ...

Researchers have dived down to the atomic scale to resolve every 'jiggle and wiggle' of atomic motion that underlies metal strength. Lawrence Livermore National Laboratory researchers have dived down ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...
