Abstract
The glide motion of a dislocation line is considered in a crystal undergoing a first-order phase transition. Within the hysteresis temperature range a trail of a metastable phase can nucleate at the dislocation and act as a dry-friction force. The strength of this force depends on the angle between the Burgers vector and the local orientation of the defect line. This fact gives rise to a new type of roughening of the line, initiated, e.g., by random point defects. For a quantitative treatment of this effect a Kardar-Parisi-Zhang--like equation of motion for the dislocation line is derived from a bulk model.
