| 英文摘要: |
| Friction stir welding (FSW) plays an important role in dissimilar metal connections. The research progress of friction stir butt welding of dissimilar aluminum alloys, aluminum alloy steel, aluminum alloy magnesium alloy, aluminum alloy copper alloy, aluminum alloy titanium alloy and numerical simulation was summarized from the aspects of welding parameters, mechanical properties of joints, intermetallic compound layer(IMCs), material flow and so on. It was pointed out that there were some shortcomings in the research on numerical simulation technology of dissimilar welding of dissimilar metal, such as numerical simulation method, material constitutive model, heat source model and boundary friction model. It was proposed to improve the friction stir welding model to provide fast and reliable technical support for practical engineering application. |
