Abstract

Titanium alloy package edge provides additional strength and stiffness to the composite fan blades of aircraft engines, which can extend the service life of fan blades effectively. However, the titanium alloy package edge was traditionally manufactured by using CNC machine tools, involving a large cutting quantity and high cost. This work proposes an innovative manufacturing method for Ti-6Al-4V titanium alloy package edge. The specific process is as follows: firstly, the reverse flattening algorithm based on the equidistant surface is employed to flatten the hollow structure of the edging, obtaining the blank with a non-uniform thickness. Then, diffusion bonding of titanium alloy sheets is achieved through electrically-assisted heating method. Subsequently, pre-forming is conducted through electrically-assisted stamping. Finally, the target component is achieved through electrically-assisted hot metal gas forming. In particular, for the electrically-assisted diffusion bonding process, the experimental results indicate that the middle section of the specimen is well welded under the conditions of a current density of 5.0A/mm², diffusion bonding pressure of 2.5MPa, and diffusion bonding time of 30 minutes. For the electrically-assisted hot forming process, ABAQUS simulation results indicated that when the temperature is 700℃ and the pressure exceeds 10MPa, titanium alloy package edge with the desired shape could be formed.
