Recrystallization Texture Transition in Fe-2.1wt.%Si Steel by Different Warm Rolling Reduction
The competition among Goss(”110”<001>),Cube(”001”<100>)and ”111”<112> recrystallization texture components depending on warm rolling reduction was investigated in Fe-2.1wt.%Si hot band,which is characterized by strong Cube at center layer.The deformation and recrystallization textures were both analyzed by X-ray diffraction technique.Warm rolling textures are composed of strong α fiber and relatively weak γ fiber with a peak at ”111”<112> for all reductions.Deformed Cube texture component can remain under 70%reduction.Cube deformation bands may be the main contributor to the deformed Cube texture component.In-grain shear bands are well developed above 80%reduction.Recrystallization texture consists mainly of Cube and Goss components for all reduction,while only weak γ fiber with a peak at ”111”<112> appears at 90%reduction.Depending on the rolling temperature of 500 °C,Cube,Goss and Cube,Goss components dominate the recrystallization texture in sequence with the warm rolling reduction increasing from 60%to 90%.This recrystallization texture transition with warm rolling reduction can be understood in terms of the number and nature of nucleation sites for various texture components.A variety of final recrystallization textures are thus proposed for non-oriented silicon steel by designing texture and microstructure of hot band and warm rolling reduction.
