Interaction between dislocations in bcc iron at high temperature

Abstract:

When a crystal deforms plastically, sources within, such as the Frank-Read source, emit dislocations, which then glide in response to the applied stress. As the dislocations move away from the source, they may encounter an obstacle, for example a grain boundary, impurity atom or locked dislocation, which they cannot overcome. As more dislocations are emitted, they 'pile up' near the obstacle, until their own stress fields acting back on the source prevent more dislocations from being produced...
