摘要：

The dielesss drawing of wires and bars is incremental plastic deformation process that has some significant advantages compared to the classic ones. In the process, the temperature and plastic deformation affect each other, so the deformation behavior is very complicated. The maximum reduction of the diameter, the influence of the drawing speed and the temperature are investigated. Changes in microstructure and hardness were investigated. As a result of the process, the grain structure was very deformed in the direction of the drawing. Any defects occurred were due to interruptions in the material microstructure caused by a high necking rate, shorter exposure time to the process temperature and low heating and cooling rates.
