Precipitation Behavior of FeTiP in Ti-added Interstitial Free High Strength Steels
چکیده انگلیسی
The precipitation behavior of FeTiP in interstitial free high strength (IFHS) steels has been studied by using a transmission electron microscope (TEM). The results show that the TiC particles, appearing at earlier stage, are more stable than the FeTiP ones during recrystallization annealing at the two given temperatures (810 °C and 840 °C). Therefore, the FeTiP particles can only be observed in the steels with sufficient amount of Ti. There is a critical forming time for the FeTiP, which is between 90 - 120 s at 810 °C and 60 - 90 s at 840 °C. The precipitation of FeTiP involves two steps, i.e. the formation of FeTi precursors and the diffusion of P. The formier step determines the reliance of Ti content for the precipitation of FeTiP, whereas the latter step leads to the difference in the critical annealing time.
