Influence of Composition and Hot Rolling Conditions on Microstructure and Texture of Nb-Ti Stabilized FSS

Abstract:

In this paper, the influence of chemical compositon on the formability of γ-fibre texture, and the hot band microstrcture has been studied. Experiments have been conducted to investigate the effect of hot rolling conditions. Nb-Ti added and Nb-Ti free specimens hot rolled in differencd hot rolling conditions have been compared. The results show that, the change in band width is dependent on hot rolling tempreture. When the hot band are rolled at the temperature of 1150-950 °C, large sizes on ferrite grain are observed, and this character is presented more obviously in the specimen with no Nb-Ti. As the incresaing of the hot rolling temperature, the intensity of γ-fibre texture decreases. γ-fibre texture presented in Nb-Ti added specimen is stronger under three hot rolling conditions.
