| Abstract Scope |
This work examines the deposition path of additive friction stir deposition (AFS-D) of AZ31 Mg Alloy. The AFS-D process was used to fabricate a 4” by 4” by 1/4” tall deposition of AZ31 Mg alloy using a differentiating raster pattern. The effect of the deposition path on material properties was examined using microstructure characterization and mechanical testing. Electron Back-Scattered Diffraction (EBSD) was utilized to evaluate the microstructure of the AFS-D specimens at high interest areas in the raster pattern compared to the microstructure of the base material. Quasi-static tests at ambient temperature were performed to evaluate the mechanical performance of the AFS-D specimens compared to that of the base material. Post-mortem analysis via scanning electron microscopy (SEM) was used to elucidate the underlying factors of mechanical response of the AFS-D specimens. Microstructure and mechanical characterization results of the AFS-D depositions of this study revealed strategies towards achieving isotropic properties. |
