AI Technical Summary
In existing titanium-aluminum alloy forging processes, the strength of the cladding decreases sharply after the cladding and billet are heated simultaneously, which cannot effectively restrain the billet, resulting in forging cracks, high forming difficulty, high mold costs, and low production efficiency.
A multi-field synergistic plasticizing forging method using titanium-aluminum alloy thermo-mechanical-electric fields is adopted. Pulsed current heating is performed inside the metal casing, the low-temperature strength of the metal casing is used to constrain the billet, and forging is carried out in a vacuum environment. The combined effect of thermo-mechanical-electric fields achieves rapid heating and high strain rate deformation.
It significantly improves the plastic deformation capacity of titanium-aluminum alloys, increases the yield to over 70%, reduces mold costs, shortens the forging cycle by 80%, and increases production efficiency by 70%.
