AMS 4905 - 6Al-4V Titanium Alloy Beta-Annealed Plate
The standard AMS 4905 covers the specifications for 6Al-4V titanium alloy plate in the beta annealed condition. It covers the specifications that are necessary for damage-tolerant titanium alloy plates, especially in the application of aircraft that require strength, fatigue resistance, and fracture toughness.
Beta annealing is done at temperatures above the β transus of the alloy being annealed. To prevent excessive grain growth, the temperature for β annealing should be only slightly higher than the β transus. Annealing times are dependent on section thickness and should be sufficient for complete transformation.
Applications of AMS 4905 Titanium Plate
AMS 4905 titanium plates are primarily used in aerospace structural components where durability and resistance to crack propagation are essential. Typical applications include:
- Aircraft airframe panels and bulkheads
- Engine mounting plates and structural supports
- Components subject to cyclic loading or high-stress conditions
- Aerospace brackets and fittings requiring high fracture toughness
What is 6Al-4V Titanium ?
6Al-4V titanium, also known as Ti-6Al-4V or Grade 5 titanium, is the most widely used titanium alloy in the aerospace industry. The 6Al-4V titanium alloy is valued for its exceptional strength-to-weight ratio, corrosion resistance, and ability to perform reliably in both ambient and elevated temperature environments.
