摘 要：<正> The variations of the dislocation structuresin the quench and 650℃ tempered steel withincrease of elongations have been investigatedby using transmission electron microscopy. Inthe small elongation stage, the boundaries betweenferrite and carbide in this steel can releasedislocations. As the elongations increase, themoving dislocations in the ferrite slip ontothe carbides. Then, the interaction betweenmoving dislocations and dislocations releasedfrom this boundaries, and the interaction betweenthe dislocations moving to the carbides in everyslip plane occurs. Thereby, the dislocationtangles around the carbides can be formed.In the large elongation stage, the dislocationtangles with high dislocation density and thedeveloped dislocation cells are formed.
