General Characteristics
The Ti6Al4V ELI titanium alloy is renowned for its high strength-to-weight ratio and excellent corrosion resistance, making it suitable for diverse applications in industries such as aerospace, automotive, medical, and more. It often replaces heavier and less efficient materials, offering reliable and cost-effective solutions.

Special Characteristics
Ti6Al4V ELI (Grade 23) is an enhanced version of Ti6Al4V (Grade 5) with reduced levels of oxygen, nitrogen, carbon, and iron, leading to improved ductility and fracture toughness. It is ideal for biomedical implants, aerospace components, cryogenic applications, and offshore equipment due to its high resistance to stress corrosion cracking in seawater.

Powder Specification
The Arcam Titanium Ti6Al4V ELI is a gas-atomized powder with particle sizes between 45 and 100 microns, ensuring safe handling. Refer to the Arcam MSDS for detailed safety information.

Post Processing
Heat Treatment: Hot Isostatic Pressing (HIP) is recommended for fatigue-loaded components with parameters of 920°C, 1000 bar, and 120 minutes.
Machining: The alloy offers good machinability with low cutting speeds, high feed rates, ample cutting fluid, sharp tools, and a rigid setup.
Welding: Ti6Al4V ELI can be welded using conventional processes, though special measures are required due to its chemical reactivity.

Chemical Specification
The alloy's composition includes 6% Aluminium, 4% Vanadium, and trace amounts of Carbon, Iron, Oxygen, Nitrogen, and Hydrogen, with Titanium as the balance. These specifications align with ASTM F136 standards.

Mechanical Properties
The mechanical properties of Ti6Al4V ELI produced via the EBM process are comparable to wrought annealed materials and superior to cast materials. Key properties include a yield strength of 930 MPa, ultimate tensile strength of 970 MPa, and a fatigue strength of over 10,000,000 cycles at 600 MPa.

Microstructure
The EBM process results in a microstructure with a lamellar α-phase and larger β-grains, offering higher density and finer grain due to rapid cooling. The material is naturally aged during the build process.
