WebApr 8, 2024 · The surface stress of the forging measured by x-rays diffraction (XRD) method was in agreement with the simulation results, and the reliability of the numerical model was verified. The cold expansion method can effectively reduce the quenched residual stress in curved frame forging. WebX-ray diffraction can be used to measure the residual stress in a material by determining the distance between crystallographic planes (d-spacings). When the material is in tension, the d-spacing increases, and when under compression, the d-spacing decreases. The d-spacings are calculated using Bragg's Law: nλ = 2dsinθ.
