| Abstract Scope |
Friction stir processing (FSP) is a thermo-mechanical treatment that engenders gradient microstructure in the material. The present work elucidates the effect of microstructure in-homogeneity on the mechanical properties of a conventional non-heat-treatable Al5083 alloy. The mechanical properties were evaluated by a high-throughput profilometry-based indentation method. The variation in properties was related to grain size and dislocation density captured through high-resolution orientation imaging microscopy. Notably, a marginal variation in the properties resulted in strain partitioning between different zones and eventually fracture during external loading. Finally, different FSP strategies were employed to enhance the overall mechanical properties will be discussed. |
