In recent years, with the advancement of titanium alloy material technology, high-strength, high-toughness, and anti-fatigue titanium alloy materials have been continuously developed and applied, and the most typical representative is Ti-5553 alloy.
The Ti-5553 master alloy has the characteristics of α+β titanium alloy and β-type titanium alloy. The tensile strength under the annealing state can reach 1080MPa. After solid-solution aging heat treatment, the tensile strength can exceed 1500MPa, and it has good toughness. Compared with the Ti-6Al-4V alloy, the alloy has the advantages of good hardenability, high strength, and good fracture toughness. It has been successfully applied to the connection between the wing of the Airbus A380 and the engine pylon.
