Recombination of a Dislocation Dipole in Ti2N

Shot peening of Ti-45Al-10Nb in air leads to partial amorphisation of the outermost layer and to the formation of a contaminant nanocrystalline (T, Al)N phase, presumably Ti2N. The figure shows dislocation recovery within a nano-crystalline grain embedded into the amorphous phase of the shot peened surface layer, as observed in situ. Three dislocations are marked by symbols. Stage (i): The isolated dislocation on the left hand side is relatively immobile. The two other dislocations are in a dipole configuration and propagate towards each other and are about to annihilate in stage (ii). Stage (iii) shows the situation after annihilation of the dipole dislocations; this is indicated by the continuous trace of the lattice planes. Observations made at room temperature with an acceleration voltage of 300 kV. It should be noted that the micrographs were sligthly compressed along the vertical direction in order to make the dislocations readily visible. The figure demonstrates the high electrical, thermal and mechanical stability of the instrument.

Graphene Layers

Twinning defects in Bilayer (flower) and Trilayer (hexagon, bottom) Oriented graphene sheets are revealed by contrast changes in this series of Warhal-inspired Dark-Field TEM images. Strain induced Moire patterns (hexagon, top) are caused by a small lattice mismatch in the first and third layers. The layers are colored by their thickness, and each of the six images correspond to a different diffraction peak, providing unique information regarding the nature of these defects.
