Type B dislocations with Burgers vectors parallel to the twofold axes of the Al 70Co 15Ni 15 decagonal quasicrystal were studied by means of electron diffraction contrast imaging and defocus convergent-beam electron diffraction techniques. Two kinds of Burgers vector of the type B dislocations were...
Not only the directions, but also the senses and magnitudes of the Burgers vectors b of dislocations in Al70Co15Ni15 decagonal quasicrystal have been determined for the first time by the large-angle convergent-beam electron diffraction technique. Rightâhand screw dislocations with b = ...

An edge dislocation in an Al70Co15Ni15 decagonal quasicrystal was studied by means of a contrast experiment and a defocus convergent-beam electron diffraction technique. The Burgers vector of this edge dislocation in six-dimensional space was determined to be (1/2 00000). The magnitudes of ...
A transition in the Burgers vector from a/2<111> to a<001> has been found to exist as a function of composition and temperature in the B2 pseudo-binary (Fe,Ni)-40Al (at%) system. At room temperature, this transition occurs at a composition between Fe-40Al-10Ni, which exhibits <...
BURGERS VECTOR POPULATIONX-RAY LINE PROFILE ANALYSISNanocrystalline Ni thin films have been produced by direct current electrodeposition with different additives and current density in order to obtain 〈100〉, 〈111〉 and 〈211〉 major fiber textures. The dislocation density, the Burgers vector ...
By means of high-temperature deformation, stacking faults, dislocations and dislocation pairs have been induced abundantly in the Al70Co15Ni15 decagonal phase. Burgers vector b, their directions, their senses and their magnitudes, of dislocations were determined by large-angle convergent-beam electron...
Through analyzing the mechanism characteristics of dislocation loop transition and extracting Burgers vector, the improved PRD method accurately identified the state of dislocation loops, and then calculated the simulation of accelerated transition process from 〈100〉 loop ...
