| Tóm tắt: | Заглавие с экрана High performance and reduced weight and cost are gaining importance in the aviation industry. There are different approaches to meet these requirements. In this study, titanium and aluminum alloys were welded using friction stir welding. The samples were divided into two groups, one of which was welded using ultrasound. Studies have shown that the strength of samples is influenced by many factors that are usually not taken into account. For example, the complexity of the interface between dissimilar materials and its roughness. It was found that the application of ultrasound during welding often increases the complexity of the interface and decreases its roughness, which generally leads to strengthening. This effect can neutralize the increase in the volume fraction of intermetallic compounds during the intensification of the welding process. The final strength consists of the number of defects, the volume fraction of intermetallics and the complexity of the interface. |
