“…Therefore, the extrusion of billets made from machining swarf mixed with a certain amount of powder may allow the powder to fill in the voids included in the extrudant, resulting in an increase in density and mechanical properties in our experiments as well. Furthermore, it is necessary to investigate the effects of machined chip size on the mechanical properties and microstructure of solid-state recycled materials because it is known that such effects are not negligible in other materials: AZ91D magnesium alloy (Hu et al, 2008) and AZ31B magnesium alloy (Wu et al, 2009). …”

“…A few papers focusing on direct recycling of Magnesium can be found in literature. In particular, the effect of size chips and extrusion ratio on the main microstructural and mechanical properties [11][12][13] and the corrosion properties of the extruded product [14] have been investigated for solid state recycled Mg alloys.…”

AZ31 magnesium alloy recycling through friction stir extrusion process

Friction Stir Extrusion is a novel technique for direct recycling of metal scrap. In the process, a dedicated tool produces both the heat and the pressure to compact and extrude the original raw material, i.e., machining chip, as a consolidated component. A proper fixture was used to carry out an experimental campaign on Friction Stir Extrusion of AZ31 magnesium alloy. Variable tool rotation and extrusion ratio were considered. Appearance of defects and fractures was related to either too high or too low power input. The extruded rods were investigated both from the metallurgical and mechanical points of view. Tensile strength up to 80 % of the parent material was found for the best combination of process parameters. A peculiar 3D helical material flow was highlighted through metallurgical observation of the specimens

“…The study proved that the recycled specimen showed superior corrosion resistance with respect to the virgin ones and also that better mechanical properties can be obtained (Chino et al, 2006b). Another interesting result is available in Wu et al (2009). These authors dealt with AZ31B magnesium alloy chips of different size recycled by hot extrusion.…”
