Abstract: The microstructure and texture characteristics of warm-rolled Ti-IF steel sheets and Ti+Nb-IF steel sheets were investigated. The results of optically metallographic observation, morphology analysis of dispersed second phase particles and texture analysis showed that the grain size and the size and quantity of second phase particles of Ti-IF steel sheets are all greater than that of Ti+Nb-IF steel sheets. In the surface layer, the texture intensity of these two steel sheets are quite different. But in the middle layer, cold rolled texture component appears in both steel sheets. The fibre texture components are (1 1 0)//ND, (1 0 2)//ND in surface layer, and (0 0 1)//ND, (1 1 1)//ND and (1 1 2)//ND in middle layer. The <0 0 1>//RD and <1 0 2>//RD appear in the surface and middle layers of Ti-IF steel sheet samples respectively, which is different from Ti+Nb-IF steel sheets.
