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 = ...

Finally, the repaired vector X∼ of GPOD is given by:(12)X∼=ΦXΓ It should be noted that, the POD makes no special assumption about the analyzed data. In addition, no restriction is exerted on the incomplete data which ensure the robustness of this method. 2.2. Augmented Burgers eq...

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 ...

Dislocation loops with Burgers vector a〈100〉 are formed in Cu-Ni alloys during 1 MeV electron irradiation in a high-voltage electron microscope at 350°-400°C. The dislocation loops are of interstitial type and pure edge in character with 〈110〉 line vectors. Some of the loops are seen...
