Comparative neutron and synchrotron X-ray diffraction studies to determine residual stress on an as-welded AA2024 plate.
In: 7th International Conference on Residual Stresses (ICRS-7), 14-17 June, Xian, China, pp. 223–228.
The residual stress field in a VPPA welded AA2024 coupon sample was measured by neutron diffraction. A similar sample was measured using synchrotron X-rays to determine the inplane strain directions. The macrostrain obtained from both sources compares well in spite of the significant difference in gauge volume and diffraction geometry. The result confirms the repeatability of the weld process and also shows good correspondence between the two diffraction processes.
