FIGURE 2.7 Dislocation climb involving vacancy (□) diffusion to edge dislocation
allowing its movement to climb from plane A to plane B. for the edge dislocation,
the direction of movement of the screw dislocation is perpendicular to b.
(a) (6) (c) FIGURE 2.9 Cross-slip of a screw dislocation XY from (a) plane A to (b)
plane B to (c) plane A. Slip always occurs in direction of Burgers vector b. Since
many dislocations in a crystalline solid are curved like the one shown in Fig.
(Courtesy of Anthony Thompson, Carnegie-Mellon University.) the Burgers vector
b2 in dislocation AB is parallel to the jog PP' , the jog is of the screw type.
Similarly, the jog QQ' in dislocation XY is found also to be of the screw type. The

This is one of the best textbooks on physical metallurgy. My preference is for Dieter's book, but that is because it was the textbook for my physical metallurgy course in graduate school. Hertzberg's book is more modern. Read full review
