“…[1,2] However, the continuous-casting hot-rolling heat treatment approach produces high-strength steel plates with inhomogeneous mechanical properties along the thickness direction. [3,4] Owing to various factors, such as element segregation during solidification, inhomogeneous thermoplastic deformation, and hardenability during heat treatment, [3][4][5][6][7][8] the hardness of steel plates typically decreases gradually from the subsurface to the core. Several attempts have been made to overcome the reduction in the wear resistance of steel due to this hardness distribution.…”

The hardness of high‐strength steel gradually decreases from the subsurface layer to the layer that is half its thickness. This hardness distribution reduces the wear resistance of steel plates. To date, there have been few reported solutions to this problem. Herein, an in situ approach is used to prepare TiC‐reinforced steel. The findings demonstrate that the introduction of TiC reinforcement enhances the wear resistance performance along the thickness direction of high‐strength steel. Although the hardness of TiC‐reinforced steel gradually decreases from the surface to the core, the wear resistance of the steel initially increases before decreasing. In addition, compared with normal steel, the wear resistance performance of TiC‐reinforced steel is increased by 15% at the subsurface, 24% at 1/4 thickness, and 31% at 1/2 thickness. This unusual phenomenon is attributed to the size features of TiC, which vary along the thickness of the plate. The proportion of small TiC particles decreases from the subsurface layer to the core, whereas the proportion of large TiC particles increases gradually. This technique can provide an avenue for improving the wear resistance of other large‐thickness wear‐resistant materials along the thickness direction.

“…As known [20], with an increase in the thickness of plate steel, its structural heterogeneity increases. At the near-surface layer of this steel plate, at a depth of up to 8 mm, it exhibits all the structural constituents found in the previous plates at deeper locations: allotriomorphic ferrite along the boundaries of former austenite grains and bainite, which does not have an internally developed subgrain structure (Fig.…”

A technique to assess microstructural anisotropy assessing by the thickness of the plate steel based on the texture analysis of the image has been developed. This technique provides for the anisotropy assessment at two dimensional levels: in the short-distance and long-distance neighborhoods, which characterize the elongation along the rolling direction of fine and coarse structural constituents, respectively. The practical approval results of this technique in the study of the microstructural heterogeneity of ferritic-bainitic steels over the thickness of 25–70 mm hot-rolled plates have been presented. It has been shown that the proposed anisotropy criteria in combination with the volume fraction of coarse packet-block regions of lath bainite as well as regions of bainite without an internal developed subgrain structure adequately estimate the microstructural heterogeneity over the thickness of plate steel and can be used for a detailed interpretation of the two-stage thermomechanical processing technology with accelerated cooling including taking into account the metallurgical inheritance of the slab.
