Quenching is an efficient manufacturing technique to improve the strength of steel after hot rolling. The benefit of this application is to enhance the mechanical properties of steel products while reducing strengthening alloying elements, e.g., C, Mn, V, Nb, and N. Quenching and self-tempering (QST) especially for H-beams is a unique material strengthening process that adopts intensive surface cooling and self-tempering. A methodological difficulty in estimating the quenching effect has been a long-standing concern in the QST application. The purpose of this study was therefore to specify quenching parameters, quantify quenching, analyze the effect, and verify the credibility of the results. Transient quenching was simulated in ANSYS to analyze heat transfer and phase transformations due to quenching. An individual concept, e.g., heat exchange, cumulative quenching infiltration, or recalescence phenomena, was merged and interpreted newly for the quenching simulation. Computational results based on theoretical approaches were well consistent with empirical studies.

“…Within this framework, the estimation of the heat transfer coefficient (HTC) is a common task [2,3,4,5,6]. In thermo-metallurgical applications [7,8], the HTC represents the most important process parameter associated with quench severity since it is closely related to the micro-structure and residual stress levels after quenching [9].…”

“…Indubitably, the results of phase transformation in the cooling stage are strongly affected by the microstructure of the steel obtained in the previous two stages (Bansal et al, 2020). The theoretical basis for considering the cooling medium is the CCT (Continuous-Cooling-Transformation) diagram of the steel (Bouissa et al, 2019).…”

“…Meanwhile, according to Ibrahim et al (2015), the microstructure of materials, especially grain size, and its importance for the longevity of materials are often ignored. In many cases, even though the hardness of the steel might achieve the desired value, the grain size observed in the microstructure image is still too coarse, leading to an increase in the brittleness of the materials (Sun et al, 2020;Bouissa et al, 2019). This might reduce the fracture toughness of materials.…”

In order to select an appropriate heat treatment process for an industrial application of S45C medium carbon steel, it is necessary to investigate the influence of technological parameters during the heat treatment process such as heating temperature, holding time and cooling medium on the microstructure and mechanical properties. In this study, the experiments were conducted in various heating temperatures, holding times and cooling mediums for specimens made of S45C steel. Then, the relationship between the microstructure and the hardness of the steel was examined. The obtained results show that the heating temperature and cooling medium strongly affect the microstructure of this steel, leading to considerable changes in the hardness. The hardness of S45C steel was markedly improved when heated above 800oC and cooled in water. Moreover, the holding time needs to be carefully calculated to obtain finer grain structure to prevent an increase in the brittleness.
