Nondestructive Neutron Diffraction Residual Stress Measurements in a Large Depth in Steels
Woo, W. ; Em, V. ; Mikula, Pavol ; Šaroun, Jan ; Seong, B. S.
Residual stresses can be effectively and nondestructively measured through a large thickness of e.g. welded plates, by means of a new design of a reactor-based neutron diffractometer. Most of the engineering neutron diffractometers have a difficulty in increasing neutron penetration capability over 25 mm total thickness in steels. However, it can be significantly enhanced up to 70 mm with 4-mm spatial resolution along the depth by using the wavelength selection in combination with neutron focusing by cylindrically bent perfect monochromator. Present paper presents details of neutron diffractometer performance and some results.
