Magnesium and its alloys are lightweight and biodegradable – properties that are attractive for structural applications in transportation and biomedical sectors. Mg has an HCP crystal structure that limits the room temperature formability, necessitating multi-stage high-temperature processing steps. In this context, we have used Friction Stir Extrusion (FSE), a severe plastic deformation process, to fabricate some basic structural building blocks such as rods and tubes. In FSE, heat input is obtained through friction between a rotating, rubbing tool and workpiece, forging and severe plastically deformation the material to the desired shape in a single step. This research utilizes commercially available AZ31 Mg alloy to prepare structural building blocks such as rods and tubes. FSE assists in engineering the microstructure of the prepared components, enabling control over its mechanical response. We will present our initial findings of the properties of the FSE processed AZ31 and how grain size and texture influence them.
