Abstract Scope |
Neutron diffraction is a powerful technique for measuring residual stress in welds due to its ability to penetrate deeply into materials at both the volumetric and atomic levels. In this experiment, three types of welds created by friction stir welding were examined: rolled-homogeneous, high-hardness, and a dissimilar weld between rolled-homogeneous and high-hardness steels. Scans were performed throughout the entire weld region, including the stir zone, thermomechanically affected zone, heat-affected zone, and base metal, with over 200 sub-scans per sample. The results were compared with existing literature on welds of armor materials or similar types produced using the arc welding process. It was found that the magnitude of tensile residual stress is smaller than that obtained through the arc welding process, with maximum peaks observed in the heat-affected zone's softened regions. |
