Learning Objectives

On completion of this TLP you should:

understand the nature of dislocations both conceptually and in a real crystal structure
appreciate the motion of a dislocation under an applied stress
be aware of the methods that can be used to reveal dislocations in a crystal structure

Before you start

Most of this package assumes no prior knowledge. However, some of the more detailed explanations use the following:

Miller index notation for specification of crystal planes and directions
Bravais lattice types

It should be possible to make use of the package even without knowledge of these concepts.

22.1: Introduction
22.2: Dislocations in 2D
22.3: Bubble Raft
22.4: Dislocation Glide
22.5: Dislocation Motion
22.6: Dislocation in 3D
22.7: Observing Dislocations
A number of ways of 'seeing' dislocations in real materials have developed since the 1950s. Only in the last few years have electron microscopy techniques advanced sufficiently to allow the atomic structure around a dislocation to be resolved.
