FCC lattice/ A6170 Defects in crystalsThe use of a geometrical device called the Burgers vector octahedron is illustrated for the notation of the Burgers vectors of those dislocations in the face-centered cubic lattice which cannot be visualized by the conventional Thompson tetrahedron. Furthermore, ...
a/2【110】和（111）并不能组成一个滑移系，FCC结构中能和（111）组成滑移系的应该有三个，在图片...

A Frank scheme based on the Thompson's tetrahedron is developed to calculate the Burgers vector of dislocations in a face-centered cubic (FCC) crystal during its plastic deformation. A Burgers circuit is located firstly in a deformed crystal with a reference circle surrounding one or more ...
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...
