| Abstract Scope |
This study investigates pearlite phase transformation in API X60 steel, widely used in pipelines due to its low alloy content and high strength. The formation, phase percentages, and morphology of the pearlitic phase determine the steel's mechanical properties. The Cahn-Hilliard phase-field model was used to simulate pearlite formation and morphology under various heat treatments. To thoroughly study pearlite morphology, both double-well and triple-well potentials were employed. Simulation results were compared with experimental data obtained via metallography and field-emission scanning electron microscopy. Unlike the double-well potential, which simulates only ferrite and cementite phases, the triple-well potential simulates a three-phase microstructure (ferrite, cementite, and austenite), aligning better with experimental results. The study found that increased cooling rates decrease interlamellar spacing and layer thickness. The triple-well potential showed an approximate 10% difference compared to experimental data, indicating superior predictions for pearlitic structures. |
