OEM Titanium Alloy Casting High Pressure Turbine

Description of OEM Titanium Alloy Casting High Pressure Turbine

The OEM Titanium Alloy Casting High Pressure Turbine is made from Ti-6Al-4V ELI vacuum consumable electrode melting. The entire process is cast in a single pass in a vacuum arc furnace, with a melting temperature of ≥1650°C and a vacuum of ≤1×10⁻² Pa, ensuring the absence of pores and inclusions. After exiting the furnace, the blank undergoes solution treatment at 1050°C for 4 h, followed by air cooling to room temperature and aging at 704°C for 8 h, achieving a stable hardness of HRC 34-36. The blades are integrally investment cast using an eight-layer zircon-silica sol shell. Dewaxing is performed at 200°C, and firing is performed at 1050°C, ensuring the formation of complex curved surfaces in a single pass with a wall thickness tolerance of ±0.15 mm. The hub-blade connection is precision-milled on a five-axis machining center to an outer diameter tolerance of ±0.02 mm, an inner hole tolerance of ±0.01 mm, and a surface roughness Ra ≤0.4 μm. Electropolishing is performed as necessary to reduce the Ra to 0.1 μm. The housing is sand-cast at low pressure, with the gate located at the bottom. This allows for controlled cooling rates and maintains an ASTM 5-7 grain size. After machining, all flow channels and oil holes are drilled using a CNC deep-hole drill, achieving a hole diameter tolerance of ±0.05 mm and a chamfer of 0.2 mm. The entire unit is balanced using a vertical dynamic balancing machine operating at 8000 rpm, with a residual unbalance of ≤0.3 g·cm. Before shipment, 100% fluorescent penetrant testing is performed, with defects showing a length of ≤0.5 mm. Randomly sampled components undergo a 550°C × 100 h high-temperature endurance test, with creep elongation ≤0.1%. Finished products are ultrasonically cleaned before vacuum packaging, each set secured in an individual wooden case.

Features of OEM Titanium Alloy Casting High Pressure Turbine

Titanium alloys offer an exceptionally high strength-to-weight ratio, which keeps the mass penalty exceptionally low for high-performance turbine components. Their density-about 4.5 g/cm³-measures almost half that of nickel-based superalloys, typically 8.5 g/cm³. In high-pressure turbine rotors, shaving even a modest mass amplifies centrifugal load magnitude. The rotor can then spin faster, allowing the engine to operate at higher efficiency. The knock-on effect on the aircraft itself also matters: less rotor mass means less structure mass to support, directly assisting overall airframe stripping.

Mid-temperature mechanical properties in titanium are outstanding. Alloys retain high strength and creep resistance over an operating envelope of 400°C to 600°C, which happens to align precisely with the environment on the rear-plane, disk, and blade surfaces of current high-pressure turbines. Operating longevity, therefore, is earned from built-in alloy selection rather than from stringent cooling-boundary designs that surplus air bleed can waste, collecting efficiency credits without weight fallout.

Titanium's workload keeps going with fatigue and impact tolerances. The disks and blades experience aggressive cyclic loading every pass, so crack progression is the first measure to pass. Leading alloys-most commonly Ti-6Al-4V and the alternatively cast Ti-6242, yet each enhanced with modern powder and processing-show crack propagation stall thresholds above engine-design load. The resultant blend of rigid growth arrest and mid-section hardness ability nurtures rotor integrity across the metal lifecycle, fending fatigue and impact while commerce resists diesel-snade.

Applications of OEM Titanium Alloy Casting High Pressure Turbine

OEM Titanium Alloy Casting High Pressure Turbines are used in gas turbines for power generation and mechanical drive. Their core technology is derived from that of aircraft engines.
