Titanium alloys are excellent candidates for aerospace applications due to their high strength-to-weight ratio and corrosion resistance. In the aerospace industry, diffusion bonding (DB) combined with superplastic forming is widely adopted to produce near net shape of titanium alloy structural parts. Of all the titanium alloys, bonding parameters have been well established for producing high-quality bonds only between Ti-6Al-4V and Ti-6Al-4V. The DB of similar alloys has been modeled successfully by many researchers. However, to date the DB time has not been modeled for dissimilar alloys. In the current work, the probabilistic model developed to predict DB time in similar titanium alloys is adapted for prediction of bonding time for Ti-64SG/Ti-6Al-2Sn-4Zr-2Mo SG dissimilar titanium alloys.
