Titanium 10V-2Fe-3Al, commonly referred to as Ti-10-2-3 or UNS R56410, is a near-beta titanium alloy engineered for extremely high strength, toughness, and deep hardenability.
It is alloyed primarily with vanadium, iron, and aluminum, producing a beta-rich microstructure that delivers superior mechanical performance, especially in thick-section forgings and critical load-bearing components.
Typical Chemical Composition
| Element | Approximate Content |
|---|---|
| Titanium (Ti) | Balance |
| Vanadium (V) | 9 – 11% |
| Iron (Fe) | 1.6 – 2.2% |
| Aluminum (Al) | 2.6 – 3.4% |
| Oxygen / Nitrogen | Low, tightly controlled |
Key Mechanical Properties
| Property | Typical Range |
|---|---|
| Tensile Strength | 1,250 – 1,800 MPa |
| Yield Strength | 1,000 – 1,200 MPa |
| Elongation | 4 – 10% |
| Density | ~4.65 g/cm³ |
These properties allow Ti-10-2-3 to achieve steel-like strength at approximately 40–45% lower weight.
Strengthening & Metallurgical Behavior
Ti-10-2-3 is strengthened through solution treatment and aging, enabling precise tuning of strength and toughness.
✔ Near-beta microstructure
✔ Excellent hardenability through thick sections
✔ High fracture toughness and fatigue resistance
✔ Stable mechanical performance after heat treatment
Fabrication Characteristics
Forgeability is excellent among titanium alloys, making Ti-10-2-3 ideal for near-net-shape forgings.
Machining is more challenging than Ti-6Al-4V due to higher strength but is manageable with optimized tooling and parameters. Weldability is comparable to Ti-6Al-4V when proper shielding and post-heat treatment are applied.
Applications
Aerospace landing gear components
Wing attachments and structural fittings
Rotor heads and airframe parts
Actuators and high-strength fasteners
Defense and space structural components
