Prediction of Intragranular Ferrite Nucleation in Steels with Ti-oxide and TiN Additions
(English)Manuscript (preprint) (Other academic)
The present work provides a method to calculate the critical diameters of TiO, TiN and VN inclusions for IGF nucleation. It is noted that the critical diameters of TiO, TiN and VN inclusions for IGF nucleation were calculated to be 0.192, 0.355 and 0.810 μm. The calculation result was in agreement with the experiment data in the steels with TiN and Ti-oxide additions. Moreover, it is the first attempt to predict the critical diameters of inclusions in the steels containing different contents of Mn and S. The critical diameters were increased with the increase of Mn content. However, the S content does not have a direct effect on the critical diameters for IGF nucleation.
