Summary: Light steel profiles are steels with medium C, Mn and Si contents. The production costs of these steels are defined by the total heat time and the Ladle Furnace (LF) processing has a large influence on heat time and costs. In this study, an Effective Equilibrium Reaction Zone (EERZ) model is developed using thermodynamic and kinetics fundamentals to optimize the LF processing of these steels, and the results show that the model can achieve a good fit to the industrial process and identify critical variables for process optimization.

Summary: This study aims to provide experimental data on the buckling and collapse behavior of hot-rolled stainless steel angle columns to aid in developing design guidelines absent in European standard. The experiments included material tests, geometric imperfection measurements, residual stress measurements, and compression tests, finding that the strength predictions in design specifications were conservative due to lower initial geometric imperfections in test columns compared to fabrication tolerances in codified design.

Summary: A simple and quick method has been developed to predict the earing profile of Al sheets solely from {200} pole figures, which was applied on 3003 type Al sheets in a hot-rolled state. It was shown that if the grain structure is uniform across the thickness of the sheet, the earing profile can be appropriately calculated from the full {200} pole figure obtained from X-ray Diffraction (XRD) texture measurements.

Summary: Titanium-clad bimetallic steel integrates the corrosion resistance of titanium alloy into structural steels, providing improved safety, serviceability, and durability. However, there is limited research on its seismic performance and fatigue behavior, hindering the development of proper design methodologies. This study investigates the low-cycle fatigue behavior of titanium-clad bimetallic steel and compares it with conventional steels.

Summary: The pursuit of weight reduction in the automotive industry has led to the use of high-strength steel sheets for structural applications. This study examined the fatigue properties of rolled steel sheets with different chemical compositions and found that the type of sheet affected the fatigue behavior and fracture patterns. The evaluation of fatigue life using different methods yielded different results for TWIP steel.

Summary: This study investigates the flexural buckling behavior of corroded hot-rolled H-section steel beams, showing that corrosion leads to a decrease in the flexural buckling strength of the beams. The failure positions and buckling half-wavelength are found to vary with the degree of corrosion.

Summary: The flow and temperature field variation of hot rolled seamless steel tube with outer diameter of 140 mm and wall thickness of 10 mm were studied by experiment and numerical simulation. It was found that the cooling characteristics of multiple jets are non-uniform under the influence of gravity and hollow characteristic. However, uniform cooling can be achieved through reasonable configuration of jet velocity.

Summary: A composite steel plate for marine construction was fabricated using 316L stainless steel and A6 carbon steel through hot rolling. The corrosion behaviors of the cladding material, carbon steel substrate, and the interface between stainless steel and carbon steel were analyzed in a marine atmosphere and seawater. The results showed significant accelerated corrosion along the interface in the carbon steel part, but the composite interface exhibited better corrosion resistance in the electrochemical tests.

Summary: This study experimentally investigated the shear behavior of steel-ultrahigh performance concrete (UHPC) composite beams and the specific effects of shear span-to-depth ratios. The results showed that the shear span-to-depth ratio significantly affected the shear behavior of the composite beams, with a decrease in shear resistance and an increase in ductility as the ratio increased. The measured ultimate shear capacity was compared to different shear design approaches, and a good agreement was found with the standard AFNOR. An analytical model for predicting the shear resistance was developed based on experimental observations and existing design methods.

Summary: In this study, non-oriented electrical steel sheets were characterized by MBN and EBSD, with the relationship between MBN and MAE found to be less significant than previously reported. Residual stress was shown to play an important role in determining the polarities of MBN, which had been ignored in previous studies. Possible reasons for the discrepancies between the results of this study and previous studies were discussed.

Summary: In this study, the microstructures and mechanical properties of quenching and partitioning (Q & P) steels prepared with hot-rolled (HR) and cold-rolled (CR) sheets at different annealing temperatures were investigated. The results showed that the HR-Q & P samples exhibited higher content of retained austenite, better elongation, and higher product of strength and elongation (PSE) compared to CR-Q & P samples. The lath-shaped retained austenite in HR-Q & P samples contributed to the homogenization of carbon in austenite grains, resulting in improved thermal stability and content of retained austenite. The lath-shaped retained austenite also exhibited higher mechanical stability than coarse blocky retained austenite.

Summary: The study demonstrates the importance of high ductility and moderate strength in Al-Mg alloys, which can be achieved through strong work-hardening abilities. Factors such as low density of pre-existing dislocations, random grain orientations, and reduced stacking fault energy contribute to the enhancement of work-hardening capacity and desirable ductility, while unevenly distributed precipitates are harmful for work-hardening and lead to reduced ductility.

Summary: In industrial steel plate production, a deep learning model was developed to predict mechanical properties based on process parameters and steel grade composition. Comparative analysis showed that the accuracy of the deep neural network model was higher than other classic machine learning algorithms. The tuned model was deployed in a real steel plant for online monitoring and control of steel mechanical properties.
