Abstract
Superplastic forming and diffusion bonding (SPF/DB) is a well-established process for the manufacture of components almost exclusively from Ti-6Al-4V sheet material. The SPF/DB with gas pressure control for honeycomb structure is investigated. The optimum parameters are as follows: bonding temperature, T = 1203 K; bonding pressure, P = 10 MPa; bonding time, t = 30 min. The effects of microstructure were carried out with the bonded samples. The microstructure shows an excellent bonding at the interfaces. The optimum parameters for the SPF/DB process are as follows: forming temperature, T = 1203 K; forming pressure, P = 0.6 MPa; forming time, t = 60 min. The distribution of thickness after SPF/DB was investigated.
