【Abstract】 The recent development on the precipitation of the second phase particles in Ti IF steels was reviewed, in which the following topics were involved: the kinds of the second phase particles in Ti IF steels; the precipitation process of the second phase particles during the hot rolling; the effect of the chemical composition and the hot rolling parameters on the precipitation behaviour. The research should be focused on studing the solubility products and precipitation kinetics, especially the interaction of several precipitates, and finding the quantitative analysis methods for precipitate in the future.更多还原
