A large single crystal of a material has the shape of a rectangular prism. The unit cell is of the material is cubic, and the edges of the crystal are parallel to the crystallographic axes, as show in the figure. The long dimension is parallel to the [001] axis of the crystal. The dimensions of the crystal are 10 mm x 10 mm x 20 mm when it is not subjected to any stresses. The crystal contains a single dislocation in the mid-plane along its length. The dislocation threads the crystal from the midpoint of the left side to midpoint of the right side, as shown in the figure. The burgers vector of the dislocation is ½[ 1 OT] 0011 a.) What kind of dislocation is it? b.) Fully describe a slip system or slip systems on which this 0101 dislocation could glide, ã1001 c.) The material has the CsCl crystal structure. Would you expect a dislocation with the burgers vector and orientation described above to be stable? That is, would you expect this dislocation to exist in the crystal as a favored configuration for a dislocation? Discuss your answer.
