Abstract
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.
