| Abstract Scope |
Current solid-state additive manufacturing methods rely on costly trial and error, motivating the development of computational models. These models, however, struggle to capture time-dependent microstructural evolution. We utilize Additive Friction-Stir Deposition (AFSD) as a representative case study for part-scale quantification of microstructure evolution at a fine spatial resolution (200 μm) by examining a liquid-nitrogen-cooled stop-action build via energy-dispersive X-ray diffraction (EDXRD) coupled with a multi-channel detector. These results inform modeling efforts by linking process asymmetry to stored plastic strain, residual elastic strain, and texture development. As such, this technique provides essential validation data for computational models, e.g. crystal plasticity, enabling future prediction of heterogenous behavior in AFSD and other additive manufacturing processes. |
