TIMETAL ® 10-2-3

Product catalog summary

Overview:
TIMETAL 10-2-3 is a high-strength, deep hardenable forging alloy developed by TIMET, primarily used in airframes and engines. It is a near beta alloy that allows for near-net shape forging techniques, offering excellent strength-toughness combinations and high fatigue life, making it suitable for safe-life designs. Common applications include aircraft structural parts such as landing gear components.

Chemical Composition:
The alloy consists of Titanium with Vanadium (9.0-11.0%), Iron (1.6-2.2%), Aluminum (2.6-3.4%), and trace amounts of Oxygen, Carbon, Nitrogen, Hydrogen, and other residual elements.

Physical Properties:
- Density: 0.168 lb/in³ (4.65 g/cm³)
- Beta Transus: 1470°F (800°C)
- Mean Coefficient of Thermal Expansion: 5.4 x 10^-6 in/in/°F (9.7 x 10^-6 mm/mm/°C)
- Tensile Modulus: 15.9 Msi (109.6 GPa)
- Compressive Modulus: 16.3 Msi (112.3 GPa)
- Shear Modulus: 6.1 Msi (42.1 GPa)
- Poisson's Ratio: 0.32

Mechanical Properties:
Guaranteed minimum mechanical properties are provided for different AMS specifications, with varying aging temperatures and section thicknesses. The ultimate tensile strength, yield strength, elongation, reduction in area, and fracture toughness are detailed for each condition.

Heat Treatment:
The alloy undergoes solution heat treatment at 50°-100°F below the beta transus for at least 30 minutes, followed by water quenching. Aging heat treatment is performed at 900°-1100°F for 8 hours, followed by air cooling.

Typical Applications:
Applications include landing gear actuators, fittings, flap tracks, fasteners, and rotor heads.

Technical Support:
Contact information for TIMET's sales offices and technical support centers in North America and Europe is provided for further assistance.
