| Abstract Scope |
Solid Phase Additive Manufacturing is an emerging technology to produce parts featuring recrystallized, fine grained, isotropic microstructure circumventing melting and solidification of the deposited material. Friction Surfacing Layer Deposition (FSLD) is currently the most suitable process to produce builds of high plasticizing temperature materials, since it does not require expensive tooling and does have economic and technical advantages for large scale manufacturing. In this study, four-layered additive structures of a NiCoFeCrCu0.12 HEA was produced successfully using FSLD. This is the first worldwide reported successful deposition of a Cu-HEA with the FSLD technology. Microstructural analysis clearly shows the combined effects of elevated temperatures and mechanical deformations on the refinement of grain sizes in the deposit. Finer grain sizes of 12 µm were measured in the layer interface compared to grain sizes of 20-30 µm in layer centers. An average micro hardness value of 176Hv was measured for the FSLD HEA layers. |
