文摘

As a new attempt, ball spinning was used to manufacture a composite tube of copper and aluminum. The interface compatibility of the composite tube during ball spinning was investigated by combining finite element method with process experiment. The experimental results are in good agreement with the simulated ones. When the composite tubular blank which is composed of inner aluminum tube and outer copper tube is subjected to ball spinning, the composite tube keeps a good synchronism in terms of plastic deformation. When the composite tubular blank which consists of inner aluminum tube and outer copper tube undergoes ball spinning, the composite tube keeps a poor synchronism in terms of plastic deformation. The phenomenon indicates that the yield strength of the inner and outer tubes plays a significant role in the interface compatibility during ball spinning of the composite tube. According to the experimental and simulated results, the interface compatibility of the composite tube during ball spinning should meet the following requirements, including boundary condition of admissible velocity field, geometrical condition of composite tubular blank, steady flow condition of surface metal, and plastic yield condition of composite tube.
