Abstract
Commercially pure Ti and Ti-based alloys produced by laser powder bed fusion (L-PBF) processes have been extensively studied. However, there are few special Ti-based alloys that are applicable to L-PBF. This work aims to study the effect of the laser power and scanning speed on the density and surface morphology of novel Ti-6Zr-5Fe alloys. The obtained results indicate that the Ti-6Zr-5Fe alloy is suitable for powder preparation. With increasing laser power and a decrease in the scanning speed, the density of the L-PBF Ti-6Zr-5Fe alloy increased, while less un-melted powder particles and a smoother surface were obtained. The present results may provide a guideline for designing special L-PBF alloys.
