2, Product Introduction:
TA15 is a high Al equivalent near alpha titanium alloy with a nominal composition of Ti-6.5Al-2Zr-1Mo-1V, mainly used for aviation load-bearing structural components that work for a long time below 500 ℃. Compared with TC4, TA15 has better thermal stability and welding performance at the same strength level, but due to its low content of beta stabilizing elements and narrow forging range, the difficulty of forging is significantly higher than TC4, making it a customized forging category that is not commonly stocked in the industry. This product is formed by free forging billet combined with die forging. The forging heating temperature is controlled below the β phase transition point, and the final firing temperature is appropriately increased to control the content of primary α phase in the range of 20%~30%, thereby achieving the best match between strength and toughness. After forging and solid solution aging treatment, the tensile strength can reach over 930 MPa, the impact toughness is ≥ 40 J/cm ², and the fracture toughness is ≥ 60 MPa · m ¹ᐟ ². The product is mainly aimed at the integrated forming requirements of key structural components such as aircraft fuselage load-bearing frames, beams, and joints, replacing multi piece welding structures with near net forging.
3, Performance index parameters of TA15 titanium alloy forging parts
Material Standard: GB/T 25137/Model Standard Remarks
Brand: TA15 (Ti-6.5Al-2Zr-1Mo-1V)
Mechanical properties (solid solution aging state): Tensile strength: ≥ 930 MPa Impact toughness: ≥ 40 J/cm ² Fracture toughness: ≥ 60 MPa · m ¹ᐟ ² The best match between strength and toughness is achieved when the content of primary alpha phase is controlled at 20%~30%.
4, Product application:
TA15 forged parts mainly serve the load-bearing structures of military aircraft and hypersonic vehicles. Typical components include the fuselage load-bearing frame, wing to fuselage docking beam, engine mounting joint body, and flap slide rail bracket. In the aerospace field, it is used to manufacture missile compartment connection frames and rocket engine thrust structural components. Due to its superior welding performance compared to TC4, TA15 is irreplaceable in load-bearing components that require subsequent welding and assembly. However, due to its narrow forging window and low yield rate, there are few domestic manufacturers with stable batch production capabilities, and it belongs to a proprietary forging category supplied by model.
