The current investigation is the study of microstructural evolution in AZ31B deposit produced using AZ31B powder employing the novel powder bed friction stir (PBFS) technique. The fabrication of the deposit using AZ31B powder involved the implementation of a suitable process parameter, specifically a rotational speed of 1200 rpm and traverse speed of 360 mm/min. Additionally, a tool design with a triple-circular protruded feature was utilized. The microstructure analysis was done using electron backscatter diffraction (EBSD). The examination focused on the resulting grain refinement, amount of recrystallization, and texture evolution.
