Experiments have recently been reported by Turner and Vreeland (1) in which the dislocation velocities in pure iron single crystals were measured. This paper describes some limited results for identical experiments on crystals containing approximately 45 ppm by weight, of carbon. These results indicate that the carbon has very little effect on the velocity of free dislocations. However strong pinning effects were observed for aged dislocations.
