摘要:A new two-layer process based on hot forming and diffusion bonding for forming a hollow titanium wide-chord fan blade with complex geometries was developed. An essential approach for optimal blank design was proposed. The present process employed a more reliable and controllable method to construct the internal ribbons, instead of complicated superplastic forming. To evaluate the practicability, a numerical method was used to investigate the thickness uniformity, structural integrity and skin defects of forming results using ABAQUS. A series of experiments were conducted to validate the simulation results. The Ti-6A1-4V alloy was adopted as the forming material, and blanks optimized by the proposed approach were used. The results show that a scaled-down version of the hollow wide-chord fan blade without defects is successfully formed. In addition, it is observed that the experimentation and simulation agree well.
