| Abstract Scope |
The Institute Max von Laue – Paul Langevin is an international research centre at the leading edge of neutron science and technology, using neutrons as a probe to investigate the structure and dynamics of a wide range of materials and components .Neutron scattering is a non-destructive technique that enhances the characterization of matter deep in the bulk. In particular, neutron diffraction is used for internal strain and stress analysis by obtaining the interplanar spacing in a polycrystalline material and extrapolating this to the macrostress estate of the material. The method is phase-sensitive and also enhances the measurement of the fullstrain/stress tensor. Furthermore, it has been developed to a common calibration protocols and reporting standards, as a part of the Neutron Quality Label (NQL) ® for residual stress. In the recent years a common CHADA and ontologies definitions have been also developed together with synchrotron methods and a common software is also being proposed. |
