Development and Optimization of High-Resolution Neutron Scattering Instruments Dedicated to Characterization and Testing of Materials of Relevance to Nuclear Energy Sector and Related Experiments in SANS, Residual Strain/Stress and Texture Studies

In this report we present the results we have received in the frame of participation in the CRP project. According to the plan of the project several experiments related namely to characterisation and testing of materials of relevance to nuclear sector were carried out. In this way two experimental methods were used: residual strain/stress measurements by neutron diffraction and small angle neutron scattering (SANS). A special attention has been paid to the following samples: Austenitic stainless steel plates with a longitudinal weld joint, Charpy-V notched specimen of low-alloy ferritic steel, 50 mm thick welds in feritic steel, austenitic single pass fillet steel welds, Ni-based CMSX4 superalloy.
