22: Introduction to Dislocations

  • Page ID

    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.
