    Energy-resolved neutron imaging for reconstruction of strain introduced by cold working
    (MDPI, 2018-02-28) Tremsin, AS; Kockelmann, W; Kelleher, JF; Paradowska, AM; Ramadhan, RS; Fitzpatrick, ME
    Energy-resolved neutron transmission imaging is used to reconstruct maps of residual strains in drilled and cold-expanded holes in 5-mm and 6.4-mm-thick aluminum plates. The possibility of measuring the positions of Bragg edges in the transmission spectrum in each 55 × 55 µm2 pixel is utilized in the reconstruction of the strain distribution within the entire imaged area of the sample, all from a single measurement. Although the reconstructed strain is averaged through the sample thickness, this technique reveals strain asymmetries within the sample and thus provides information complementary to other well-established non-destructive testing methods. © 1996-2021 MDPI
