OS04F125 Modern and Historical Engineering Concerns Investigated by Neutron Diffraction

抄録

The ENGIN-X beam-line is mainly used to determine residual strains/stresses deep within the interior of bulk engineering components. It is mainly used by scientists and engineers for the development of modern engineering processes and structural integrity investigations. However, the instrument is also used by scientists with archeological interests who are constantly looking for nondestructive methods to discover the past, by relating to the manufacturing and working conditions of the investigated object. ENGIN-X diffraction and transmission mode can be a very useful tool to measure in high spatial resolution strains, phase transitions, material composition in bulk material and surface coatings as well as in historical or archeological artifacts. The complexity of the shapes and sizes of the samples measured on ENGIN-X varies significantly between experiments, and this required the development of better planning, simulation and control software, SScanSS. In this paper an overview of recent developments in strain scanning on ENGIN-X and a highlight of current scientific research are presented.
