ABSTRACT
This study delves into the intricate relationship between quenching mediums—brine, engine oil, and water—and the hardening characteristics of low carbon steel. Through a systematic investigation, we aimed to determine the optimal quenching medium that enhances the hardness of low carbon steel, thereby contributing to improved wear resistance and durability. Our research encompassed a comprehensive examination of the microstructure of quenched steel samples, enabling us to identify and understand the phases and structures formed during the hardening process with each quenching medium. Further, we assessed and compared the mechanical properties, including tensile strength, impact toughness, and yield strength, to ascertain their influence on material performance.
By establishing correlations between the cooling rates associated with brine, engine oil, and water quenching and the resulting microstructures and hardness of low carbon steel, we provided valuable insights into the relationship between cooling dynamics and material properties.
Our findings not only contribute to a deeper understanding of the quenching process but also offer practical guidelines and recommendations for industries seeking to implement effective and sustainable quenching processes for low carbon steel. These guidelines aim to optimize heat treatment processes, thereby enhancing the mechanical properties of low carbon steel and facilitating its utilization across various industrial applications.
