Effect of Cooling Rate on As-Cast Texture of Low-Carbon Steel Strips During Rapid Solidification
We investigated the dendrite structures and the as-cast textures of low-carbon steel strips cast at different cooling rates in order to relate the δ-ferrite dendrite structure with the ferrite phase texture. Observations revealed that the orientation intensity of the texture component {111}<uvw> was stronger than the texture component {001}<uv0> in the as-cast steel strips obtained at different solidification cooling rates. These two texture components show a roof-shaped variation with the gradual decrease of the solidification cooling rate, reaching a maximum intensity at a cooling rate of about 2.0 K/s. This suggests that the solidification rate strongly influences the as-cast texture of low-carbon steel strips through changing the δ-ferrite dendrite structure.
