Amorphous nanocrystalline alloy test method
Part 2 - Strip lamination factor
1 Scope
This section GB/T 19346 specifies the method of measuring the lamination factor of amorphous nanocrystalline alloy strip by the plane pressure method and the coil method.
This section applies to the use of rapid quenching amorphous nanocrystalline alloy strip (hereinafter referred to as tape) lamination factor measurement, in which the plane
The pressure method is suitable for measuring the lamination coefficient of strip with rectangular core, adhesive block, etc. The lap method is suitable for lamination coefficient of strip for toroidal iron core
measuring.

3 Terms and definitions
GB/T 15019 and defined by the following terms and definitions apply to this document.
3.1
Lamination factor lamination factor
The ratio of the cross-sectional area of the magnetic material to the total cross-sectional area of the stack.
4 Plane pressure method to measure lamination factor
4.1 Measurement principle
A section of the tape is cut into a certain number of sheet samples of a certain size, and then stacked in the same direction to form a sample stack neatly. In the regulations
The maximum thickness of the sample stack in the direction perpendicular to the casting direction of the strip is measured. According to the sample laminated quality, length, width, maximum thickness
Degree and material density and other parameters to calculate the lamination factor.
4.2 main equipment
4.2.1 General requirements
4.2.1.1 Lamination coefficient measurement system consists of pressure mechanism, line displacement sensor, clamping and moving mechanism (see Figure 1).
4.2.1.2 In order to avoid the impact of magnetic field or sample fragments on the measurement results, the various structural components in the system should be made of non-ferromagnetic materials.
4.2.1.3 The strength and rigidity of various structures in the system shall meet the requirements of measurement accuracy.
