摘要：

Welding fillers containing various amounts of 30 nm nano-Al2O3 particles were fabricated using friction stir processing and used to improve the mechanical properties of the welding zone. Single-pass welding was made using gas tungsten arc welding. To achieve a uniform distribution of the nanoparticles, friction stir processing was applied to the welding zone. The even distribution of nanoparticles, the removal of welding defects and grain size refinement led to significant improvements of the tensile properties and hardness of the welding zone.
