burgers vector 单位burgers vector 单位 The Burgers vector is a vector that represents the magnitude and direction of a lattice distortion or a dislocation line in a crystal lattice. It is denoted by the symbol b. The units of the Burgers vector depend on the specific crystal structure and can...

If the Burgers vector is limited to basic ones, the identification can be made with little tilting of the specimen. The smallness of the tilt angle and the narrowness of the dislocation image allow one to analyse relatively dense dislocation structures. The present technique is recommended as a ...
In this paper, a comprehensive molecular dynamics (MD) study is conducted concerning the effects of subsequent cascades on previously formed dislocation loops, particularly changes in their Burgers vectors induced by cascades. We reveal the atomistic mechanism behind the Burgers vector transitions and ...
