A critical evaluation of the microstructural gradient along the build direction in electron beam melted Ti-6Al-4V alloy [PDF]

, 2019
It is generally recognised that electron beam melted (EBM) Ti-6Al-4V alloys exhibit a microstructural gradient along the build direction, but there have been some inconsistent experimental observations and debate as to the origin and magnitude of this ...
