The diffusion bonding (DB)/superplastic forming (SPF) manufacturing pr
ocess, for titanium 6A1/4V material, has been developed within British
Aerospace for the manufacture of military aircraft components. Diffus
ion bonding of titanium alloys offers the potential for parent metal j
oint strengths, and when combined with SPF, complex aircraft component
s offering significant cost and weight savings can be manufactured. Th
is paper briefly describes the DB/SPF development programme and the ma
nufacture of the Tornado heat exchanger ducts and European Fighter Air
craft (EFA) foreplane components.
