“…1 shows the appearance of the machining swarf. As can be seen from the figure, the machining swarf obtained by side milling is needle-shaped and spirally twisted of length 25-30 mm and width 1 mm [27]. On the other hand, the machining swarf obtained by lathe turning is found to be curled, short swarf of length 5-30 mm, width 1.5 mm, and thickness 0.5 mm.…”

“…The cleaned machining swarf was then placed in a cylindrical container and compacted at a pressure of 303 MPa [27,28] under room temperature to form billets of diameter 20.5 mm and height approximately 25 mm. The compacts were unloaded immediately after the loading pressure reached 303 MPa.…”

“…Recently, another study [24] aimed at producing a composite material including nano-particles from machining chips via hot extrusion, and a new method was proposed to produce clad plates from iron chips by using hot rolling [25]. Almost all of the abovementioned methods require precompaction of the machining swarf, the technical details of which have been reported elsewhere [26] literature published before 2010 can be found in our previous paper [27]. Extruded sections are elongated metal products that have a complex configuration of the cross section, represented by angles and channels.…”

“…Similarly, highly directional distribution of aluminum oxides from the chips surface can be expected. Numerous reports have shown that profiles extruded from chips exhibit mechanical properties that are comparable to its cast and extruded counterparts ( Ref 9,16). However, it is worth noticing that all results reported in the literature are based only on tensile test results, performed for samples machined along the extrusion direction.…”

The direct production of aluminum from bauxite ores is known to be a very energetic-intensive operation compared to other metallurgical processes. Due to energy issues and the rapid increase in aluminum demand, new kinds of aluminum production processes are required. Aluminum waste recycling, which has an advantage of lowering the cost of electric power consumption, is considered to be an alternative route for material manufacturing. In this work, the way of reusing aluminum EN-AC 44000 alloy scraps by hot extrusion was presented. Metal chips of different sizes and morphology were cold compacted into billet form and then hot extruded. Mechanical properties investigations combined with microstructure observations were performed. Mechanical anisotropy behavior of material was evaluated on the base of tensile test experiments performed on samples machined at 0°, 45°, and 90°, respectively, to the extrusion direction. It was found that the initial size of the chips has an influence on the mechanical properties of the received profiles. Samples produced from fine chips revealed higher tensile strength in comparison to larger chips, which can be attributed to a refined microstructure containing fine, hard Si particles and Fe-rich intermetallic phases. Finally, it was found that anisotropic behavior of chip-based profiles is similar to conventionally cast and extruded materials which prove good bonding quality between chips.
