Refractory metal single crystal crystal orientation determination method
1 Scope
This standard specifies the X-ray diffraction method to determine the angle between the crystal orientation of the cubic refractory metal single crystal and the surface normal of the macroscopic sample.
This standard is applicable to the determination of the angle between the crystal orientation of the cubic refractory metal single crystal and the normal direction of the surface of the macroscopic sample.

3 Terms and definitions
The following terms and definitions defined in JY/T 009 apply to this document.
3.1
φ axis
The axis on which the sample stage rotates around the normal to the sample surface.
3.2
ω angle
The angle between the incident X-ray and the sample surface.
3.3
ω scan
Continuously change the ω angle and record the measurement mode of the diffraction intensity.
4 Principle
The cross-section or cutting surface of the single crystal will deviate from a certain low-index crystal plane by a few degrees. The deviation angle is the single crystal crystal orientation and macro
Observe the normal angle (off angle) of the sample surface.
When a beam of X-rays is incident on the crystal plane of the index, the index in the crystal represents a set of atomic structures that are parallel to each other and equally spaced.
When the optical path difference between adjacent planes satisfies the Bragg equation, diffraction will occur. At this time, the incident X-ray and the crystal plane
The included angle is called the Bragg angle and is denoted as θB. Use a counter to detect the diffraction line, and determine the direction of the crystal plane according to the position where it appears, and
The deviation of the crystal plane from the cross section or cut surface can be calculated by the azimuth relationship between this direction and the normal direction of the sample surface.
5 Equipment
5.1 The X-ray diffractometer is composed of X-ray source, parallel light accessories, sample stage, and detector, and should meet the requirements of JB/T 9400.
