Question

Which of following statements are correct for describing the Burgers vector?

(A) a vector between the nearest adjacent array of atoms
(B) is parallel to the motion of edge dislocation
(C) is perpendicular to the motion of edge dislocation
(D) is parallel to the motion of screw dislocation
(E) In BCC, one of the Burgers vector is (a/2) [111]
(F) In FCC, one of the Burgers vector is (a/2) [111]
(G) In BCC, one of the Burgers vector is (a/2) [111]
(H) In FCC, one of the Burgers vector is (a/2) [110]

Answer 1

The Burgers vector is a vector between the nearest adjacent array of atoms and it is parallel to the motion of screw dislocation.

Step-by-step explanation:

The correct statements for describing the Burgers vector are:

(E) In BCC, one of the Burgers vectors is (a/2) [111]

(F) In FCC, one of the Burgers vectors is (a/2) [111]

The Burgers vector is a vector between the nearest adjacent array of atoms and it is parallel to the motion of screw dislocation.

In edge dislocation, the Burgers vector is perpendicular to the motion of the dislocation.
