摘要
TC4(Ti-6Al-4V)钛合金板材超塑成形/扩散连接(SPF/DB)组合工艺的可行性和对影响钛板SPF、SPF/DB的主要工艺因素。着重阐述某机框段和舱门的研制情况,提供了合理的工艺参数和流程。
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.
