Structural and thermal characteristics of Ti6Al4V (Ti64) metal powders for direct energy deposition

Ti6Al4V metal powder has been widely utilized in direct energy deposition (DED) of additive manufacturing (AM) technology, especially in aerospace applications. However, to secure excellent weldability between metal powder and substrate requires a proper understanding of heat-dissipation energy/crea...
