How does heat treatment of amorphous core materials affect performance?

Amorphous iron core is a new type of core material with excellent magnetic properties, mechanical properties and corrosion resistance, which is widely used in transformers, inductors and other power electronic equipment. Heat treatment is a common processing of amorphous iron core materials, through the control of heat treatment process parameters can improve the microstructure and properties of amorphous iron core materials, thereby improving their performance.

Amorphous iron core manufacturers say that the heat treatment of amorphous iron core material performance impact is mainly manifested in the following aspects:

1. improve the hardness and strength: heat treatment can eliminate internal stress and intergranular defects, enhance the hardness and strength of amorphous iron core materials, improve its resistance to deformation and fatigue resistance. In particular, the use of appropriate tempering treatment can further improve the mechanical properties of amorphous iron core materials, making them more suitable for high-strength and high-load working environment.

2. Improve magnetic properties: the magnetic properties of amorphous core material is one of its important performance indicators, heat treatment can be reasonably controlled by processing temperature and processing time and other parameters, optimize the magnetic domain structure and hysteresis characteristics of the material, effectively improve the permeability, coercivity and iron loss and other magnetic performance indicators, to improve the energy efficiency and performance of transformers and inductors.

3. Improve corrosion resistance: amorphous iron core materials are susceptible to corrosion and oxidation during long-term use, heat treatment can improve the material's surface oxide layer and grain boundary structure, improve its corrosion resistance and oxidation resistance to prolong its service life and stability.

In general, heat treatment can effectively improve the hardness, strength, magnetic properties and corrosion resistance of amorphous iron core material, improve its comprehensive performance and reliability, and lay a solid foundation for its application in the field of power electronics. Therefore, in the preparation of amorphous iron core materials, it is necessary to pay attention to the selection and control of the heat treatment process to achieve better performance.
