Dislocation Drag Mechanisms, High Velocity Dislocations,and Twinning

The switching of a magnetic field while plastically deforming a zinc crystal causes a change in stress which is associated with electron-dislocation interactions. In this paper the dependence of this change in stress on strain-rate, field strength, and temperature will be presented. In addition, the connection between electron-dislocation interactions, dislocation velocities, and the occurrence of twinning in zinc will be established.
