Abstract:To investigate the low-cost and short-process recycling technologies for aluminium alloys, recycled chip-based Al-Si-Cu-Fe alloys were fabricated by spark plasma sintering (SPS) and hot extrusion. Microstructural observations by optical microscopy and scanning electron microscopy indicated that the recycled alloys could achieve good metallurgical bonding between the chips by fragmenting the alumina films on the chip surface by spark plasma sintering and hot extrusion after hot compress. The hot extruded recycl… Show more
