Robotic diffractometer PELICAN

The most critical technical characteristic of any product is the presence of stresses within it, which determine its suitability for use under specific conditions. Residual stresses remain in any part after its processing. In addition, residual stresses can arise due to phase transformations, irradiation by high-energy particles, non-uniform heating and cooling, etc. In this regard, information about the presence of residual stresses is critically important for monitoring and influencing the reliability and service life of mechanical products. X-ray diffraction is an effective non-destructive method for diagnostics and analysis of residual stress distribution. The specialized X-ray diffractometer PELICAN enables residual stress analysis in various, including hard-to-reach, points on the surface of large-scale objects made of different metals and alloys.
