General Characteristics
Titanium and its alloys, such as Ti6Al4V, are renowned for their high strength-to-weight ratio and excellent corrosion resistance. These properties make them suitable for diverse applications in industries like aerospace, automotive, medical, and more. Titanium often replaces heavier and less durable materials, offering economic and durable solutions.

Special Characteristics of Ti6Al4V ELI
Ti6Al4V ELI (Grade 23) is a variant of Ti6Al4V (Grade 5) with reduced levels of oxygen, nitrogen, carbon, and iron, enhancing its 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: Ti6Al4V ELI parts are machinable with low cutting speeds, high feed rates, ample cutting fluid, sharp tools, and a rigid setup.
Welding: The alloy can be welded using conventional processes, though special measures are required due to its chemical reactivity.

Chemical and Mechanical Properties
The chemical composition includes 6% Aluminium, 4% Vanadium, and trace amounts of Carbon, Iron, Oxygen, Nitrogen, and Hydrogen, with Titanium as the balance. Mechanical properties include a yield strength of 930 MPa, ultimate tensile strength of 970 MPa, and a Rockwell hardness of 32 HRC. The material exhibits excellent fatigue strength and a modulus of elasticity of 120 GPa.

Microstructure
Parts manufactured using the EBM process have a superior microstructure compared to cast materials, featuring a lamellar α-phase with larger β-grains and finer grain due to rapid cooling. The build chamber's elevated temperature results in a naturally aged condition.
