Studies of diffusion bonding were made for Ti–4.5Al–3V–2Fe–2Mo alloy sheets. The process conditions of pressure, temperature and time required to produce a mechanically sound bond were investigated for several surface finishes. The integrity of the bonds was evaluated using optical metallography, shear strength measurements and fractography. Sound bonds were produced in the pickled sheets in 4 h with an applied stress of 2.0 MPa at 800°C. In the polished sheets, the time and the temperature required were reduced to 2 h and 775°C, respectively, at the same stress. It was revealed that diffusion bonding of Ti–4.5Al–3V–2Fe–2Mo is attained around the same temperatures as those for its superplastic forming. A cellular panel was successfully produced with this alloy, combining its low temperature superplastic forming and diffusion bonding processes.
