摘要：
The hot rolling experiment investigates into the relationship between the microstructures and the mechanical properties of Nb-Ti microalloyed steels with various Ti contents.The results indicate that the effect of the bainite fraction of Nb-Ti microalloyed steels on the yield strength of the steels is not related to Ti content,while the slope of the Hall-Petch relationship decreases with the increase of Ti content.Accordingly,the Misra model for the yield strength of Nb-Ti microalloyed steels is modified,and the factors which cause the change in the slope of Hall-Petch relationship are discussed.
