| Abstract: |
| The goal of this paper was to study a new compound procedure of superplastic deformation /laser welding composite procedure to fabricate TC4 multi-layer structures.The superplastic deformation of the lap laser welded specimens was carried out,and the microstructures both as weld and after deformation were analyzed.The results indicated that Ti-6Al-4V laser lap weld joint could bear the superplastic deformation process and the fracture happened in the base metal,and a four-layer component was made to prove the practicability of LW/SPF. |
