Abstract
Texture of low carbon microalloyed steel sheets with bainitic microstructure produced by TMCP (thermo-mechanical controlled processing) was investigated using EBSD (electron backscatter diffraction) technique. Samples with high and low penchant for fission formation (secondary cracks at the fracture surface) were investigated. Formation of fission relates with the elongated areas of grades which have uniform orientation (001)[110]. Probably the formation of these areas is a result of features of g→α transformation at different parameters of TMCP.
