| Abstract: | This paper briefly introduces practicability of superplastic forming/diffusion bonding (SPE/DB) of TC4 (TI-6A1-4V) titanium alloy sheet and effect of main proc2ssing factors, such as forming temperature, compressing rate, pressure and holding time, on SPF and SPF/DB. The processing condition for some air frames and loading doors are described and reasonable processing parameters and procedures are provided. The problems of blowing bulging input gas, high-temperature protection and mould unloading of parts and their solutions are provided.Test results show that obvious technical and economic benefit can be obtained. |
