Korean Society of Metals and Materials Spring Academic Conference Student Session Award / Kim Ye-rim (Master's Program in New Materials Engineering, Graduate School of Science and Technology, Class of 2023)
Kim Ye-rim, a student in the Department of New Materials Engineering at Kookmin University, who is part of Professor Pil-Ryung Cha's research team (Materials Computational Modeling Laboratory), received the “Best Top 20 Student of the Year” award at the 2025 Korean Society of Metals and Materials Spring Academic Conference (held from April 23-25, 2025, at the Jeju International Convention Center).
The title of the presented paper is “Development and Validation of a Phase-field Model for Fe-N Nitriding Processes.” This study developed a numerical model capable of precisely simulating nitrogen diffusion and phase transformation processes during nitriding, and validated its effectiveness by comparing the results with experimental data. It complements the limitations of existing experiment-based analyses and provides a foundation for quantitatively predicting microstructure formation under various process conditions.
In this study, the phase-field model was used to continuously analyze the formation and evolution of the ε phase, γ′ phase, and α phase, and dynamically tracked interface movement and phase distribution changes, overcoming the limitations of existing discrete analysis methods. Kim Yeo-rim quantitatively analyzed the trends in microstructure changes according to process variables and proposed the potential for optimizing the nitriding process and prediction-based design strategies.
