17 MSE 2090: Introduction to Materials Science Chapter 4, Defects in crystals Dislocations—Linear Defects Dislocations are linear defects : the interatomic bonds are significantly distorted only in the immediate vicinity of the dislocation line. This area is called the dislocation core . Dislocations also create small elastic deformations of the lattice at large distances. Dislocations are very important in mechanical properties of
