The technique utilizes the unique penetrating power of the neutron into most engineering materials, combined with the sensitivity of diffraction, to measure the separation of lattice planes within grains of polycrystalline engineering materials, thus providing an internal strain gauge. The strain is then converted to stress using calibrated elastic constants. It was just over ten years ago that the initial neutron diffraction measurements of residual stress were carried out, and during the ensuing decade measurements have commenced at most steady state reactors and pulsed sources around the world. So swift has been the development of the field that, in addition to fundamental scientific studies, commercial measurements have been made on industrial components for several years now. The use of neutrons is ideally suited to the determination of triaxial macrostress tensors, macrostress gr | | 出版日期 | Book 1992 | | 关键词 | Metall; X-Ray; alloy; composite; diffraction | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-2797-4 | | isbn_softcover | 978-94-010-5242-9 | | isbn_ebook | 978-94-011-2797-4Series ISSN 0168-132X | | issn_series | 0168-132X | | copyright | Springer Science+Business Media Dordrecht 1992 |
