The application of amorphous nanocrystalline magnetic materials will be affected by environmental factors. The following is a detailed introduction:

Ⅰ. Physical environment

1. Temperature:

The magnetic properties of amorphous nanocrystalline magnetic materials are sensitive to temperature. In a low-temperature environment, the atomic thermal motion of the material weakens, the magnetic permeability may decrease, and the coercive force may increase, which will affect its magnetic transmission and energy conversion efficiency in a low-temperature environment. In high-temperature environments, the atomic thermal motion of materials intensifies, which may lead to changes in the magnetic domain structure, reducing the saturation magnetic induction intensity and increasing magnetic losses, which in turn affects its working stability and service life in high-temperature environments.

For example, in the aerospace field, the performance of amorphous nanocrystalline magnetic materials may be affected by the extreme low temperatures in space and the high temperatures upon re-entry into the atmosphere.

2. Humidity:

A high-humidity environment may cause corrosion to amorphous nanocrystalline magnetic materials. Especially when there are defects or impurities on the surface of the material, moisture can easily invade into the interior of the material and trigger a chemical reaction, resulting in a decrease in the performance of the material. In addition, changes in humidity may cause expansion or contraction of the material, affecting its dimensional stability and consistency of magnetic properties.

3. Mechanical stress:

In practical applications, if amorphous nanocrystalline magnetic materials are subjected to mechanical stress, such as tension, compression, bending, etc., the magnetic domain structure of the material will change, causing the magnetic permeability to decrease and the coercive force to increase. For example, in the engine compartment of a car, parts made of amorphous nanocrystalline magnetic materials may be subject to vibration and shock, affecting their magnetic properties.

Ⅱ. Electromagnetic environment

1. External magnetic field:

Under the action of a strong external magnetic field, the magnetic domain structure of amorphous nanocrystalline magnetic materials will be rearranged, which may lead to changes in performance parameters such as saturation magnetic induction intensity and magnetic permeability. When using amorphous nanocrystalline magnetic materials near some high-magnetic field equipment, the impact of external magnetic fields on their performance needs to be considered to ensure their normal operation.

2. Electromagnetic radiation:

In a high-frequency electromagnetic radiation environment, amorphous nanocrystalline magnetic materials may increase eddy current losses and hysteresis losses, reducing their energy conversion efficiency. For example, in places with strong high-frequency electromagnetic radiation such as communication base stations, the amorphous nanocrystalline magnetic materials used need to have good anti-electromagnetic radiation properties.

Ⅲ. Chemical environment

1. Corrosive gas:

In some industrial environments or special occasions, corrosive gases such as sulfur dioxide, chlorine, etc. exist. These corrosive gases may react chemically with amorphous nanocrystalline magnetic materials, destroying the surface structure and internal components of the materials, resulting in a decrease in their magnetic properties.

2. Contact with chemical substances:

When amorphous nanocrystalline magnetic materials come into contact with certain chemicals, chemical reactions or physical adsorption may occur, changing the surface properties and magnetic properties of the materials. For example, in the chemical industry, if amorphous nanocrystalline magnetic materials come into contact with chemical substances such as organic solvents, acid and alkali solutions, their performance and service life may be affected.
