Effect of travel speed and stress relief on thin Ti-6Al-4V laser wire deposits

The effect of two travel speeds on thin Ti-6Al-4V buildups produced by Laser Wire Deposition (LWD) has been investigated. A travel speed set at 1.4 mm/s promoted recrystallization of columnar prior β grains into horizontal prior β grains. It was associated with lower strength hardly meeting minimum...
