“…[2][3][4][5] However, it is metallurgically difficult to refine aluminum scraps by the remelting processes. Hence, most of the current recycling processes are down grade recycling 6) and there are some problems such as contamination of iron, silicon and so on from aluminum scraps, 3) resulting in a reduction in service properties.…”

Corrosion and Mechanical properties of a recycled 5083 aluminum alloy by solid state recycling have been compared with those of a virgin extrusion which was processed from the ingot block. In the solid state recycling, the machined chips were extruded at 723 K with an extrusion ratio of 44 : 1 in air. As a result of the salt immersion tests, the mass loss of the solid recycled specimen was not less than twice of that of the virgin extruded specimen. The deterioration in corrosion properties for the solid recycled specimen was attributed to the excessive contamination of iron which promoted galvanic corrosion. As a result of tensile tests, the solid recycled specimen exhibited a good combination of high strength and high elongation to failure at room temperature. The excellent mechanical properties for the solid recycled specimen were attributed to the refined microstructure. However, the elongation to failure of the solid recycled specimen at elevated temperatures more than 573 K was lower than that of the virgin extruded specimen. The contamination of oxide particles is likely to be responsible for the lower elongation in the solid recycled specimen.

“…In order for the innovation of the current melting-based recycling technologies, the concept of industrial ecology via a solid-state recycling has been discussed. 1) Some easily deformed metals, e.g., copper and aluminum, are easy to be recycled by solid-state technologies. For example, a process of severe plastic deformation (SPD) termed high-pressure torsion was found to be effective to consolidate machining chips of pure copper and AlSi 8 Cu 3 alloy.…”

It is of practical significance to improve the recycling value of hard-to-deform titanium wastes by means of melting-free technologies. One such technology, severe plastic deformation in the form of equal channel angular pressing (ECAP) was used to consolidate chips of commercial purity titanium. Electron backscatter diffraction (EBSD) was used to resolve the microstructure into high angle grain boundaries (HAGBs, with misorientation ²15°) and low angle grain boundaries (LAGBs, <15°). The strain energy stored in HAGBs and LAGBs were considered to be the primary driving force of dynamic recovery (DRV) and dynamic recrystallization (DRX). As a result of DRV and DRX, the formation of microstructure was analyzed by evaluating the stored energy for various ECAP conditions. The ductility of the recycled titanium was analyzed by verifying the failure mode according to the inspection of the fracture surface of the tensioned specimen with scanning electron microscopy.
