ACB (France) and its sister company Cyril Bath (USA) have a long experience in the fields of hydraulic presses and metal forming for the aerospace industry. This experience is particularly focused on the manufacturing of structural and engines parts. The purpose of this presentation is to show how the combination of both activities in the fields of Hot Forming/Sizing and Superplastic Forming results in continual progress and how recent evolution open new fields of applications. First, both processes will be shortly introduced. The advantages of Hot Forming, Superplastic forming and Diffusion Bonding technologies will be demonstrated regarding current customer’s requirements. To conclude an overview of on-going research programs will be made to present strong advantages of dual presses combining Hot Forming and Superplastic processes.

Integrated Structures

Superplastic forming and diffusion bonding (SPF/DB) processes have been growing mature and titanium SPF/DB components have found wide application in aerospace industry. With the development of industrial SPF/DB technology, the size of SPF/DB components become bigger and bigger, and the shapes of components become more complex. However, the component sizes are limited by equipments, dies and the size of sheet. SPF/DB combined with welding technologies could be one of the possible solutions to form larger and more integrated structures due to many advantages compared with conventional process. This paper studied the combination processing of SPF and other welding methods besides diffusion bonding, such as electron beam welding and laser beam welding, and explained the experiments performed in different processes, including SPF after welding plate and welding plate after SPF. The results show that the material exhibits both reasonable formability and excellent mechanical properties. Application samples such as covers were manufactured by the combination processing. Furthermore, prospects of the combining technology were discussed at the end of paper.

The diffusion bonding (DB)/superplastic forming (SPF) manufacturing process, for titanium 6A1/4V material, has been developed within British Aerospace for the manufacture of military aircraft components. Diffusion bonding of titanium alloys offers the potential for parent metal joint strengths, and when combined with SPF, complex aircraft components offering significant cost and weight savings can be manufactured. This paper briefly describes the DB/SPF development programme and the manufacture of the Tornado heat exchanger ducts and European Fighter Aircraft (EFA) foreplane components.

Market Pressure

Superplastic Forming and Diffusion Bonding (SPF/DB) have provided some of the lightest, strongest, corrosion resistant, elegant and complex structures ever produced. Thus “At Boeing, SPF is now considered as a baseline design option for many large assemblies” (Dan Sanders, 2000). However, in an ever increasingly cost conscience world, will the process flourish or decline? Cost is the element most scrutinised by society, and is often considered more important than achieving a required specification or delivery of a project on time. In this paper an analysis of the global value of SPF and SPF/DB products will be provided by industrial sector and material type. The cost of the current technology, such as capital plant, consumable materials and labour overheads, will be compared to the current price of SPF products and the degree of ‘market pressure’ to reduce such costs will be assessed. Such pressures may arise from potential threats from competing technologies, fuel costs or environmental considerations. However, if lowering the ‘carbon footprint’ of the process, and its cost, could be achieved, together with the production of components and structures of improved weight to strength ratio, SPF technology could be elevated to the first, and principal, choice of designers worldwide.
