EFFECT OF HOT-ROLLING CONDITION ON THE DEVELOPMENT OF TEXTURES IN ULTRA-LOW CARBON-STEEL

The development of hot and cold rolling textures in Ti-bearing ultra low carbon steel has been investigated laying emphasis on effects of various processing parameters such as slab reheating temperature, hot rolling temperature, partition of hot rolling and cold rolling reductions. {225}[554], {001}[110] and {225}[110] are suggested as attractors of texture components during deformation, which have 29.5-degrees rotation relationship to a common [110] axis with respect to each other. In chaotic rotation of grains during deformation, if the material lies under shear condition, {225}[554] appears as a main texture component. Due to crystallographic instability, {225}[554] easily alters to {001}[110] and further to {225}[110] under plane strain condition and/or with increasing rolling reduction.
