Ti-10V-2Fe-3Al Precision Casting Aerospace Engine Components Manufacturer
Introduction
Ti-10V-2Fe-3Al is a near-beta titanium alloy developed for aerospace engine applications requiring high strength-to-weight ratio, excellent fracture toughness, and superior fatigue resistance. As a professional precision casting manufacturer, we produce high-performance Ti-10V-2Fe-3Al aerospace components using vacuum investment casting, achieving ±0.05 mm dimensional accuracy and <1% porosity for critical engine systems.
Our castings are ideal for rotating and structural elements in aerospace propulsion assemblies, where lightweight and high-performance titanium parts are essential.
Core Technology: Precision Investment Casting of Ti-10V-2Fe-3Al
We utilize advanced vacuum investment casting for Ti-10V-2Fe-3Al to prevent oxygen contamination and ensure metallurgical integrity. Ceramic shells (8–10 layers) are used with mold preheating at 950–1050°C. Casting temperatures are maintained around 1650°C under high vacuum (<10⁻³ torr). Controlled cooling rates (20–50°C/min) provide uniform beta-phase transformation and grain size control (0.5–2 mm).

Case Study: Ti-10V-2Fe-3Al Aerospace Engine Component Production
Project Background
An aerospace OEM required lightweight turbine case brackets and engine pylon fittings for a commercial jet engine program. Ti-10V-2Fe-3Al was selected for its superior strength-to-weight ratio. We produced vacuum-cast parts meeting AMS 4983 standards with final dimensions controlled within ±0.05 mm and heat treatment optimized for beta-phase retention.
Typical Aerospace Engine Component Applications
Fan Frame Brackets (e.g., GE LEAP, PW1100G): Cast Ti-10V-2Fe-3Al parts reduce weight while maintaining mechanical integrity under cyclic stress and moderate heat.
Engine Mount Lugs and Links: High-strength castings absorbing engine vibrations and thrust loads with excellent fatigue resistance.
Bearing Support Structures: Static precision castings requiring tight tolerances and stable performance across a wide temperature range.
Bypass Duct Support Frames: Lightweight cast frames designed to handle dynamic loading and pressure pulsations without deformation.
These components are essential to both structural stability and vibration resistance in turbofan and turbojet engine assemblies.
Manufacturing Solutions for Ti-10V-2Fe-3Al Components
Casting Process Wax assemblies are invested into high-purity ceramic shells. Vacuum casting is performed at ~1650°C with mold temperatures around 1000°C. Controlled cooling and mold removal prevent cracking and promote uniform grain structure.
Post-processing After casting, parts undergo Hot Isostatic Pressing (HIP) at ~925°C and 100 MPa to close internal pores. Solution treatment and aging are applied to achieve full mechanical property potential.
Post Machining CNC machining is performed to achieve final precision for mounting faces, hole diameters, and sealing features. Where tight internal features are required, EDM is applied. Deep hole drilling is used for hollow cooling or fastener access passages.
Surface Treatment Components may receive shot peening or stress-relief polishing. Optional titanium oxidation barrier coatings are applied for parts in hot-air zones or salt-laden environments.
Testing and Inspection All parts undergo X-ray nondestructive testing, CMM dimensional validation, mechanical testing, and metallographic analysis to verify grain refinement and β-phase distribution.
