The difference between magnetic annealing and general annealing
Author:
The difference between 1. magnetic annealing and general annealing
Magnetic annealing and general annealing are both heat treatment technologies, but their difference lies in the nature and purpose of the annealed material.
Magnetic annealing is mainly used in the heat treatment process of magnetic materials such as iron and steel, aiming to reduce the hysteresis loss of the material and the magnetic energy inside the magnetic domain, thereby improving the magnetic conductivity and magnetic induction strength of the material. In the magnetic annealing process, the material will be subjected to high temperature heating and high-intensity magnetic field, so that the magnetic moments of the magnetic domains are rearranged and combined to form a new magnetic domain structure.
General annealing is widely used in the processing and heat treatment of various metals, alloys and non-metallic materials to improve the microstructure and properties of materials and eliminate residual stress and deformation during material processing. In the general annealing process, the material will be affected by heating and cooling, forming a certain thermal cycle, thereby changing its organization and performance.
Applications of 2. magnetic annealing and general annealing
Magnetic annealing is mainly used in electronics, communications, medical and other fields, such as inductors, transformers, superconducting materials, etc. In electronic products, magnetic annealing can improve the inductance and quality factor of the inductor, making the product more stable and reliable. In the medical field, magnetic annealing is widely used in MRI and other diagnostic equipment.
General annealing is used in the processing, molding and manufacturing of various metal products, such as auto parts, aircraft parts, precision instruments, etc. In the processing of metal products, general annealing can improve the toughness, ductility and plasticity of the material, making it easier to form and process.
In short, although magnetic annealing and general annealing are annealing technologies, their application fields and purposes are very different. The correct selection of the appropriate annealing process and parameters can improve the performance and quality of the material and meet the application requirements of different fields.

Precautions for powder metallurgy heat treatment
The core of heat treatment of powder metallurgy parts is temperature control. Due to the high porosity of powder metallurgy parts, deformation and cracking are easy to occur at high temperatures. Therefore, it is necessary to strictly control the heating temperature and holding time according to the heat treatment requirements of different materials to prevent thermal deformation and cracks of the parts.

Principle and precautions of ultra-deep cooling treatment
The principle of ultra-cryogenic treatment is to improve the performance of metal materials by changing their crystal structure. The cryogenic treatment temperature is very low, which can make the metal atoms move freely, thus changing the crystal structure and enhancing the hardness and toughness of the material.
