| Abstract: |
| To get bimetal composited T-shaped conveniently, a new hydroforming process is introduced in this paper. A simple forming equipment is developed and Al/Cu bimetal composite T-shaped tubes are formed by it. The influence of different process conditions on forming results is studied and the bimetal hydraulic bulge forming rule is obtained on analysis. Using scanning electron microscopy (SEM) and other equipment, the microstructure of the bimetal interface is observed. Experimental results and analysis show that this processing is simple, the forming cycle is shortened, the forming cost is saved to a certain extent and the bonding quality of the interface is good enough. The feasibility and reliability of this new technology are verified simultaneously. |
