Neutron Diffraction Measurements of Residual Stresses for Ferritic Steel Specimens over 80 mm Thick

Popis výsledku v původním jazyce

The maximum thickness for ferritic steel specimens' residual stress measurements using neutron diffraction is known to be about 80 mm. This paper proposes a new neutron diffraction configuration of residual stress measurements for cases that are over 80 mm thick. The configuration utilizes a neutron beam with a wavelength of 1.55 angstrom diffracted from the (220) plane with a diffraction angle (2 theta) of 99.4 degrees. The reason for the deep penetration capability is attributed to the chosen wavelength having enough intensities due to the low cross-section near the Bragg edge and the reduced beam path length (similar to 16 mm) reflected by the large diffraction angle. Neutron diffraction experiments with this configuration can decrease strain errors up to +/- 150 mu epsilon, corresponding to a stress of about +/- 30 MPa.
