This technology, which is used in the production of large, complex components involves the diffusion bonding of multiple layers of titanium sheet at selected points, which can then be superplastically formed using inert (argon) gas to inflate the sheets into the shape of a hollow die. This process is extremely temperature and pressure sensitive and allows for the creation of much more complex shapes, no spring back and significantly higher elongation, in comparison to other traditional metalforming methods.
At the point the ambient temperature argon forming gas is admitted into the heated component, the gas expands, increasing its volume and hence its pressure if not adequately controlled. The new Group Rhodes patent enhances the control of this process by compensating for atmospheric pressure.
Applied extensively to the lightweighting of components within the aerospace and automotive industries, Superplastic Forming and Diffusion Bonding play an integral part in performance improvement, carbon reduction and effective implementation of low-emission technologies.
Speaking on the achievement, technical director of Group Rhodes, Peter Anderton said: “This new innovation serves to enhance Superplastic Forming accuracy, reduce scrappage and improve productivity. The recent grant of patents in Europe and China reinforces Group Rhodes’ position as a leading global provider of this technology.”
