Question
1. Correctly identify each of type of dislocation shown below... Bungers vector Dislocation line 2. Which of the following is an INCORRECT statement... The Burgers vector corresponds to a dislocation's slip direction. The net plastic deformation for the motion of both edge and screw dislocations is the same. The Burgers vector has a magnitude that is equal to the unit slip distance. The Burgers vector is parallel to the dislocation line for edge dislocations. Slip distance is minimized along planes with the highest planar density. a. b. c. d. e.Explanation / Answer
1. a) this crystal has a edge dislocation ( line defect) as it is missing some atoms along an edge. Dislocation propagates along the crystal. Here also the burgers vector will be perpendicular to the dislocation line.
b) the dislocation here is screw dislocation and the burgers vector is parallel to the dislocation line.
c) The dislocation here is also edge dislocation and the burgers vector is perpendicular to dislocation line.
2.) the statement d is incorrect . The burgers vector is perpendicular to the dislocation line for edge dislocation.
