Abstract

An investigation was performed on the static strain aging behavior of warm-rolled low carbon steel during a nearly 1-year aging period, from the view point concerning with influence of changing the deformation speed and cooling media. Mechanical response of the examined material during aging period was evaluated through variations occurred in strength and hardness of the warm-deformed steel. It was shown that changing the rolling speed as well as cooling rate, may result in the occurrence of different metallurgical phenomena, consequently altering the aging kinetics of the material. It was also found that by increasing rolling speed, an increase in the value of hardness and UTS takes place, while changing the cooling rate to a higher value can cause a more considerable variation in the mechanical behavior of warm-rolled samples throughout the aging period. From the industrial point of view, the experiments conducted in this work is in agreement with the practical conditions of high temperature rolling processes with long interpass times, such as Steckel rolling process.
