Microstexture of Ti-6Al-4V obtained by direct energy deposition (DED) process

, 2016
The microstructure of bulk samples prepared by CLAD® additive manufacturing of Ti-6Al-4V (Ti64) powder have been investigated by means of SEM and phase reconstruction. The CLAD® technique (laser blown powder processing) developed at IREPA LASER provides very high cooling rate promoting the formation of the martensitic α’ phase in the form of thin ...

Analysis of AISI 316L steel processed by direct energy deposition (L-DED)

Journal of Physics: Conference Series
Abstract The aim of this study was to perform a metallographic analysis of a thick-walled plate made of powdered austenitic steel AISI316L by direct energy deposition (L-DED) process. After the plate was manufactured, it was heat treated and surface machined.

Wire-arc directed energy depositing high-ductility Cu-10Fe immiscible alloy with a hierarchical microstructure

Smart Materials in Manufacturing
In this work, a thin-wall Cu-10Fe (10 wt%) immiscible alloy component is fabricated by wire-arc directed energy deposition (WA-DED), leveraging the high energy absorption of the electric arc for copper alloys and its high deposition rate.
