An aLternative Heat Treatment Recovery of the Magnetic Properties of a Non-Grain Oriented Fe-Si Steel After Cutting

This work investigates the effects of an alternative heat treatment on magnetic losses and their components - hysteresis loss, excess loss and classic loss - in non-grain oriented (NGO) steel. The importance of this study lies in the search for strategies to optimize the magnetic performance of materials used in industrial applications. We carried out experiments using heat treatment at 700 ° C, 800 ° C and 900 ° C on NGO steel and evaluated its implications on magnetic losses. The results reveal that heat treatment at 700 ° C was highly effective and significantly influenced the different components of magnetic losses. We observed that excess and hysteric losses were the most impacted by heat treatment, demonstrating a particular sensitivity of these components to specific thermal conditions. In-depth analysis of these changes provides valuable insights for optimizing the magnetic behavior of NGO steel in practical applications. This study contributes to the understanding of the crucial role of heat treatment in modifying the magnetic properties in materials such as NGO steel and have important practical implications for the selection and development of magnetic materials in sectors that demand improved energy efficiency and magnetic performance.
