摘要：

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 degrees 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 Fe2Ti, 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.
