TA10 Turbocharger Components Isothermal Forging Factory
Introduction
TA10 is an advanced titanium alloy (Ti-6Al-2Sn-4Zr-2Mo) designed for excellent high-temperature strength, creep resistance, and fatigue durability. With a tensile strength of ~940 MPa and exceptional thermal stability up to 500°C, TA10 is highly suited for high-speed turbocharger components subjected to extreme thermal cycling and centrifugal forces.
At Neway AeroTech, we specialize in isothermal forging of TA10 turbocharger components, achieving fine-grain microstructures, superior mechanical properties, and precise dimensional tolerances for demanding automotive, aerospace, and industrial turbo systems.
Key Manufacturing Challenges for TA10 Turbocharger Components
Maintaining chemical composition (Ti base, Al ~6%, Sn ~2%, Zr ~4%, Mo ~2%) for mechanical and thermal stability.
Controlling grain refinement through isothermal forging at ~950–980°C to optimize fatigue and creep resistance.
Achieving tight dimensional tolerances (±0.02 mm) is critical for aerodynamic balance and turbocharger efficiency.
Ensuring superior surface finishes (Ra ≤1.6 µm) reduces drag and improves performance.
Isothermal Forging Process for TA10 Turbocharger Components
The production process includes:
Billet Preparation: High-purity VAR TA10 billets selected for chemical homogeneity.
Isothermal Forging: Precision forging at ~950–980°C under constant die and billet temperatures to minimize residual stresses and achieve uniform fine-grain microstructure.
Controlled Cooling: Slow cooling to stabilize microstructure and prevent beta grain coarsening.
Solution Treatment and Aging (STA): Heat treatment cycle optimizes α+β phase distribution for strength and toughness.
Precision CNC Machining: Final machining achieves aerodynamic profiles and tight tolerances critical for rotor balance.
Surface Finishing: Polishing or shot peening improves fatigue resistance and surface integrity.
