Contribution to Internal Friction from a Dislocation Pileup with Application to Deformed Single Crystals

Abstract

The contribution to the internal friction resulting from a group of dislocations confined to a single slip plane, and forced against a barrier, is calculated. Application of the result to the long-range-stress theory of work hardening, in conjunction with the Seeger theory of the Bordoni peak, suggests that, in deformed single crystals, an internal friction peak of constant magnitude should be observed throughout stage II of the stress-strain curve.
