In this paper, the formability of Ti-TWBs at different elevated temperatures is experimentally investigated. Ti-TWBs made of Ti-6Al-4V sheets with thicknesses of 0.7mm and 1.0mm are manufactured. Then, the tensile test and forming test at elevated temperatures, ranging from room temperature to 600°C, have been carried out to determine the mechanical properties and the formability of the prepared Ti-TWBs respectively. The effects of elevated temperatures on both the forming and failure behaviors of the Ti-TWBs are examined by comparing with that of the Ti-6Al-4V base metal. It is found that the formability of the Ti-TWBs at room temperature with a dissimilar thickness combination is lower than that of their base metal, whilst the formability of both the Ti-TWBs and their base metal increases with increasing forming temperature. In addition, failures have often been found at the thinner base metal during the Ti-TWB forming, provided that the quality weld is attained without defect.
