| Abstract Scope |
Energy-dispersive X-ray diffraction (ED-XRD) utilizes polychromatic synchrotron X-rays to non-destructively characterize crystalline materials, similar to conventional angular-dispersive X-ray diffraction. However, unlike its counterpart, ED-XRD allows for selective measurement of material information from a discrete 3D volume within a bulk sample and its surrounding environment, akin to time-of-flight neutron diffraction. This is achieved by using a polychromatic incident beam and measuring at a fixed scattering angle with an energy-dispersive detector. The resulting gauge volume provides an opportunity to map both phases and strain in complex material systems. This presentation focuses on the application of ED-XRD for non-destructive residual stress measurement of engineering components, highlighting its advantages and limitations in practice through real-world examples. |
