X-ray diffraction (DRX); X-ray diffraction

One of the techniques used to estimate macroscopic residual stresses by measuring crystal lattice deformation.

The principle of X-ray diffraction is based on the irradiation of a sample by a monochromatic beam of X-rays, the diffracted waves of which are collected according to the Bragg condition:

Knowing the wavelength of the incident ray λ and the diffraction angle θ, we can determine the...
