This standard replaces the standards previously issued as. --- GB/T 7704-1987, GB/T 7704-2008. Nondestructive testing - Determination of X - ray stress1 ScopeThis standard specifies the X-ray stress measurement principle, terms, symbols, determination methods, equipment, samples, measurement procedures, reports and measurement results Evaluation. This standard applies to have sufficient crystallinity, at a specific wavelength of X-ray irradiation can be continuous Debye ring of fine grain, non-woven Isotropic polycrystalline material.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. JB/T 9394 X-ray apparatus specifications 3 Terms and definitions, symbols 3.1 Terms and definitions The following terms and definitions apply to this document. 3.1.1 Residual stress residualstress In the absence of external or external torque under the conditions of the internal components or materials exist and maintain their own balance of macroscopic stress. 3.1.2 Diffraction peak diffractionpeak The distribution curve of X-ray diffraction intensity along the reflection angle under the condition of Bragg's law. Note. The angle of reflection refers to the angle between the extension of the incident X-ray and the reflection of the X-ray. 3.1.3 Diffraction angle diffractionangle 2θ The angle between the extension of the incident X-ray and the diffraction line, that is, the diffraction peak angle. Note. 2θ is also used to refer to an arbitrary reflection angle without reference to diffraction angles. 3.1.4 Full-width fulwidthathalfmaximum; FWHM The diffraction peak removes the width at 1/2 of the maximum intensity behind the substrate unrelated to the Bragg diffraction. See Appendix A 3.1.5 Diffraction crystal plane azimuthangleofdiffractioncrystalplane The angle between the normal of the diffraction crystal plane and the normal of the sample surface. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 7704-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 7704-2017_English as soon as possible, and keep you informed of the progress.
