Deformation and fracture mechanics of engineering materials
Updated to reflect recent developments in our understanding of deformation and fracture processes in structural materials. This completely revised reference includes new sections on isostress analysis, modulus of rupture, creep fracture micromechanicsms, and many more.

When an edge dislocation is present in the lattice, the circuit does not close (Fig.
2.3). The vector needed to close the Burgers circuit (X'X) is called the Burgers
vector b of the dislocation and represents both the magnitude and direction of slip
2.7 DISLOCATION-DISLOCATION INTERACTIONS Since dislocations of the
same sign will repel one another and not coalesce, they will tend to pile up (each
with a unit Burgers vector) against a barrier on the slip plane (Fig. 2.17). As one ...
Burgers vector of PP', however, is b2 — the same as dislocation AB to which it
belongs. Since b2 and PP' are normal to one another, PP' is of the edge type. It
may be shown that this jog does not impede the movement of the dislocation AB.

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
