Abstrakt: The EBSD method is used to study the grain structure of low-carbon low-alloy pipe steel sheets processed by controlled thermomechanical processing (TMCP). It is shown that changing the parameters in the mathematical apparatus of the device software for orientation microscopy leads to obtaining significantly different basic characteristics of the grain structure of the material, which are the misorientation angle for intercrystalline boundary detection and the minimum size of crystals taken into account. The orientation microscopy allows us to identify areas with homogenous crystallographic texture, with evaluating their morphology and size, which are the sites of brittle crack propagation in the process of steel fracture after TMCP.
