摘要:

 超塑成形/扩散连接技术是利用钛合金在低应变速率、合适的温度环境下伸长率高和变形阻力小的特点,在一次加热条件下同时完成气胀成形和扩散焊接,制造空心带夹层零件。选择典型的钛合金双层板中空构件为研究对象并制定成形工艺方案,采用有限元分析方法,模拟板件在超塑性状态下的成形过程,观测其在模腔内的气胀成形过程。其次通过分析成形构件的壁厚分布情况,调整并确定气压力-时间曲线用于指导工艺试验。最后对构件进行工艺试验和质量分析,取得不同压力模式下的扩散连接金相组织,以及与数值模拟相同取样点处的气胀成形壁厚数据,验证数值模拟结果与实际成形结果的偏差。

 Superplastic forming/diffusion bonding technology utilizes the characteristics of high elongation and low deformation resistance for titanium alloy under low strain rate and suitable temperature environment, and simultaneously completes inflatable forming and diffusion welding under one-time heating condition to manufacture hollow parts with interlayer. Therefore, for the typical hollow components of titanium alloy double-layer plate, its forming process plan was formulated and the forming process of the plate in the superplastic state was simulated by the finite element analysis method, then the inflatable forming process in the die cavity was observed. Secondly, by analyzing the wall thickness distribution condition of the formed components, the gas pressure-time curve was adjusted and determined to guide the process test. Finally, the process test and quality analysis of the components were carried out, and the metallographic structure of the diffusion bonding under different pressure modes as well as the wall thickness data during the inflatable forming at the same sampling point as the numerical simulation were obtained to verify the deviation between the numerical simulation and the actual forming results.
