Non-destructive test method for residual stress analysis by X-ray Diffraction

Residual stresses are the mechanical stresses present in an unloaded component. They generate an elongation of the crystal lattice depending on the elastic properties of the material and the direction under consideration. As long as no external forces act on the component, the residual stresses within the component volume balance each other out completely and equilibrium prevails.
