Abstract

The invention belongs to the technical field of crystal texture measurement, and particularly relates to a method for measuring orientation deviation angle of oriented silicon steel through X-ray diffraction, including the steps of firstly, fixing a light pipe to the negative divergence of a theoretical diffraction angle, and utilizing a probe to scan to explore with large step to acquire probablediffraction angle by the standard of generating the diffraction peak; further, reducing the scanning range, gradually reducing scanning step, and finally determining the diffraction angle and deviation angle by the standard of the maximum diffraction peak intensity. By the method, accurate diffraction angle and orientation deviation angle of oversized-grain oriented silicon steel can be obtainedsimultaneously. Besides, the method has the advantages of simple sampling, low requirements on equipment, convenience in use and accuracy reaching 0.01 degrees.

Description

technical field

[0001] The invention belongs to the technical field of measuring crystal texture, in particular to a method for measuring the orientation deviation angle of oriented silicon steel through X-ray diffraction. Background technique

[0002] Silicon steel can be generally divided into two types: non-oriented silicon steel and oriented silicon steel. Oriented silicon steel is mainly used to orient the magnetic field. In the case of similar composition, the magnetic induction of oriented silicon steel is almost only related to the degree of deviation of the Gauss grain orientation, that is, the closer the Gauss grain is to the ideal (110)<001> orientation, the The higher the magnetic field strength. Therefore, paying attention to and accurately measuring the degree of deviation between the crystal plane of the parallel surface and the (110) plane plays an important role in the quality control of grain-oriented silicon steel. The current methods for measuring...
