The document discusses Ti6Al4V titanium alloy which is commonly used in additive manufacturing. Some key points: - Ti6Al4V is the most widely used titanium alloy due to its good machinability and mechanical properties like strength and corrosion resistance. - It has applications in industries like aerospace, medical, and automotive where high strength to weight ratio is important. In medicine it is used for implants and prosthetics due to its biocompatibility. - Parts made from Ti6Al4V powder using Arcam's EBM process have mechanical properties comparable to wrought materials and better than cast materials. The microstructure is also finer grained than cast materials.
