The superplasticity of the Ti-6Al-6V-2Sn alloy for different temperatures was evaluated by single-sheet free blowing. The optimal superplastic temperature for the Ti-6Al-6V-2Sn alloy was found to be 850 C. Diffusion bonding of Ti-6Al-6V-2Sn and 304 stainless steel was carried out in a vacuum. The interface of both bonded alloys was examined by EPMA. The concentration profile of Ni exhibited a peak at the interlayer and a valley adjacent it, whereas that of Cr exhibited a peak where Ni showed the valley. X-ray diffraction (XRD) analyses showed that the Fe{sub 2}Ti, NiTi, and CrMn intermetallic compounds and the Cr element formed at the interface. The thickness profiles of the blown specimens were measured and compared with theoretical calculations.
