Crack tip dislocations in silicon single crystals were observed by combining high-voltage electron microscopy and electron tomography. Cracks were introduced by an indentation method and dislocations were introduced around the crack tip by keeping the indented sample at high temperatures for several hours. The number of dislocations emitted from the crack tip was controlled by changing the hold...
Abstract Background: Chronic neglected dislocation of the shoulder joint can be defined as a neglected dislocation for more than a 3 week period. However, it has been shown that the negligence could range from a 24 hour period to 6 months1. Depending on age, signs, symptoms, etiology and types of dislocation, conservative treatment or surgical intervention could be considered. Methods: In t...
We report high-resolution transmission electron microscopy (HRTEM) observation of a high density of dislocations with edge components (;10 m ) in nanocrystalline (NC) body-centered cubic (bcc) Mo prepared by high-pressure torsion. We also observed for the first time of the 1⁄2,111. and,001. pure edge dislocations in NC Mo. Crystallographic analysis and image simulations reveal that the best way...
