Objectif Neutron diffraction will be used for the validation and calibration of portable non-destructive techniques for stress measurement, such as ultrasonic and magnetic methods. For tests and calibration typical specimens for different applications will be used. First, cold rolled disks prepared for a forming process will be considered. Here the combined influence of residual stress and texture of the cold rolling process is of interest. Secondly, tensile specimens of ferric Cr-steel and of Zr-based alloys will be investigated under external load conditions, which will make it possible to obtain the anisotropic elastic constants and to follow the relaxation of internal stresses that depend on plastic deformations and texture. Finally, more complicated objects of welded steel plates (Cr-Mo steel of13mm thickness and Mn-Ni reactor steel of 27mm thickness) will be considered. The neutron diffraction measurements will be carried out mainly at the high resolution Fourier diffractometer at the Laboratory of Neutron Physics, in Dubna. The investigations there will be carried out in collaboration with experts from St. Petersburg Institute of Nuclear Physics, the University of Ancona and the Joint Research Centre in Petten. Specialists from the Fraunhofer Institute for Non-destructive Testing in Dresden and Saarbrucken will give assistance and perform the measurements by untrasonic and magnetic methods.
