Abstract Scope |
Friction extrusion (FEx) is a solid-state materials’ processing technique that is capable to extrude bulk, chips or powder into a solid extrudate via friction and plastic deformation. The process operates at comparably low temperatures, i.e. below the material’s melting temperature, achieves a fine-grained microstructure and offers unique opportunities in the alloy design, which can hardly be achieved via fusion-based approaches. A significant knowledge gap lies in the processability of friction extruded wires, for instance, with perspective to usage of this material for additive manufacturing. To contain the FEx-characteristic microstructure, the solid-state layer deposition approach of friction surfacing (FS) was approached. FEx material was successfully deposited via FS and, in comparison to common (hot-extruded) material, the FEx material presents significant differences in terms of FS deposition behavior, consumption, efficiency, and geometry of the resulting FS layer. The differences are a result of the microstructure and the process parameters necessitate adaptions. |
