Abstract:

This study explores the dislocation density and configuration in fully pearlitic steel wires during the cold wire drawing process by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The XRD results show that the dislocation density increases from 1·1×1014 m-2 to 1·4×1015 m-2, with the drawing strain increasing from 0 to 1·65. Measurement methods by XRD and TEM for the dislocation density are compared. Dislocation cells, walls and tangled dislocations are observed as the main dislocation substructures in ferrite lamellae. The dislocation cell size is related to the width of the ferrite lamellae, which is gradually reduced with increasing drawing strain. © W. S. Maney & Son Ltd. 2014.
