“…The quenched samples were prepared at different process times, and the quenching cooling rate was 40 °C s −1 . A quenching rate of 40 °C s −1 is commonly used by scholars [ 29,30 ] for steel samples, as it could effectively preserve the high‐temperature microstructure morphology and ensure reliable results for grain size statistics. The quenched sample was grounded and polished, and then corroded by saturated picric acid solution.…”

Clarifying the austenite grain growth law in the thin slab casting and rolling (TSCR) process can provide theoretical guidance for the control of austenite grain in the slab. Starting with the austenite nucleation during solidification process, the growth law of austenite grains is methodically studied throughout the TSCR continuous casting and soaking process. The results show that the austenite growth is not interrupted during the TSCR continuous casting and soaking process. The austenite grain growth in the continuous casting process accounts for more than 70% of the total growth. The growth rate of austenite in the continuous casting cooling process is always faster than that when reheated to this temperature. Compared with the holding temperature and holding time, the final size of austenite grains in the TSCR process slab is most affected by the continuous casting cooling rate. In addition, compared with the traditional process, the growth rate of austenite in TSCR process is faster at the end of soaking.

“…To achieve this, engineering the steel's microstructure is crucial, involving the design of microstructures with multi-phase, metastable, and multiscale features ranging from micro-to nano-length scales (Yapp and Blackman, 2004;Toloui and Militzer, 2010). These steels require highly controlled processing to achieve the desired strength and toughness through a combination of small grain size and fine precipitate distribution enhanced by using micro-alloying with elements such as Nb, V, and Ti, which leads to grain refinement and precipitation hardening, which significantly increase the strength of the steel (Roy et al, 2020b). Thermo-mechanically controlled processing (TMCP) involves austenite conditioning, controlled rolling, and accelerated cooling to further refine the microstructure and improve the mechanical properties (Gong et al, 2016).…”

This study explores the microstructural characterization of pearlite phase transformation in high-strength low-alloy API X60 steel, which is used in pipelines. Understanding the formation, phase percentages, and morphology of the pearlitic phase is crucial since it affects the mechanical properties of the considered steel. In this research, a phase-field model, particularly the Cahn–Hilliard approach, was used in order to simulate the formation and morphology of the pearlite phase in response to different heat treatments. Both double- and triple-well potentials were considered for comprehensively studying pearlite’s morphology in the simulations. The simulation results were then compared with experimental outcomes obtained by metallography and field-emission scanning electron microscopy analyses. Considering the double-well potential can help simulate only two phases, ferrite and cementite, which is less compatible with the experiment results than the triple-well potential, which gives the possibility of simulating a three-phase microstructure, ferrite, cementite, and austenite, and a better match with experimental data. The study revealed that as the cooling rate increases, the interlamellar spacing and layer thickness decrease. Additionally, the difference between experimental and simulation results using triple-well potential was approximately ∼10%. Therefore, triple-well potential formulation predictions have better agreements with experimental results for the development circumstance of pearlitic structures.
