| Abstract Scope |
Complementary techniques of characterization were applied aiming to investigate the response of the Ti-13%Nb-13%Zr alloy to orthopedic grafts requirements after produced by additive manufacturing (AM). The Laser Powder Bed Fusion (L-PBF) process consists of powder deposition followed by the material fusion by a laser that can be remotely controlled, allowing the achievement of high complex geometry parts.
This process was applied operating with spherical powders (resulted from plasma atomization) and irregular powders (resulted from hydride-dehydride obtention). After L-PBF, the material showed a totally martensitic microstructure both by XRD and microscopy. Optical microscopy was fundamental on the formulation of a processing window able to show which are the best process parameters to produce dense parts made of both different powders. |
