“…What part the particles play in the damage of the material, however, is still uncertain. Sarkar et al, [7,8] in agreement with Datsko and Yang, [1] have shown that an increasing amount of constituent iron-rich particles not only influences the bendability of an alloy, but also the tensile ductility. Ragab and Saleh [9] and Bettaieb et al [10,11] took into account void growth and coalescence in modeling of bendability.…”

“…THE AA5xxx (Al-Mg) series aluminum alloys were used extensively for applications in automotive structures [1][2][3][4][5] due to their high work hardening rate and good formability. [6] These alloys are presently made from primary aluminum and recovered process scrap.…”

We have investigated the influence of melt conditioning by intensive shearing on the mechanical behavior and microstructure of Al-Mg-Mn-Fe-Cu-Si alloy sheet produced from a small book mold ingot with high added impurity content. The melt conditioned ingot has fine grains throughout its cross section, whereas a conventionally cast ingot, without melt shearing, has coarser grains and shows a wider variation of grain size. Both needle-shaped and coarse Chinese script iron bearing intermetallic particles are found in the microstructure at the center of the conventionally processed ingot, but for the melt conditioned ingot, only fine Chinese script intermetallic particles are observed. In addition to the iron bearing intermetallics, Mg 2 Si particles are also observed. The ingots were rolled to thin sheet and solution heat treated (SHT). During rolling, the iron-based intermetallics and Mg 2 Si particles are broken and aligned along the rolling direction. Yield strength (YS), ultimate tensile strength (UTS), and elongation of the intensively melt sheared and processed sheet are all improved compared to the conventionally cast and processed sheet. Fractographic analysis of the tensile fracture surfaces shows that the clustered and coarse iron bearing intermetallic particles are responsible for the observed reduction in mechanical properties of the conventionally cast sheet. We have shown that by refining the initial microstructure of the ingot by intensive shear melt conditioning, it is possible to achieve improved mechanical properties at the final sheet gage of an AlMgMn alloy with a high content of impurities.

“…In these cases, secondary metal produced from recycled products saves 93% of energy consumption compared with that required for primary aluminum production. However, the Fe content of scrap aluminum alloys can increase to unacceptable levels, owing to the iron pickup effect [4]. Wrought aluminum alloy compositions of recycled metals have been studied by Das and Gesing [2,5], who indicated that recycled aluminum alloys typically have an Fe content of ∼1.00 wt%.…”

“…Wrought aluminum alloy compositions of recycled metals have been studied by Das and Gesing [2,5], who indicated that recycled aluminum alloys typically have an Fe content of ∼1.00 wt%. A high Fe content is considered to reduce the formability of aluminum alloys [4,6,7]. Hemming is an important forming process for manufacture of lightweight aluminum alloy closures, where the final step in the forming route of a body closure is joining of the outer panel to the inner panel through a hemming operation.…”

“…Hemming is an important forming process for manufacture of lightweight aluminum alloy closures, where the final step in the forming route of a body closure is joining of the outer panel to the inner panel through a hemming operation. This [4,[8][9][10][11]; however, the development of recycle-friendly automotive aluminum alloys with high Fe content has yet to be reported. Therefore, low cost [3] and recycle-friendly automotive aluminum alloy sheets with suitable hemming properties would be highly desirable.…”

Unavoidably, Fe impurities are mixed into Al alloys during recycling of aluminum automotive parts. High Fe content recyclefriendly aluminum alloy sheets (RASs) are discussed in terms of their applications to car body parts and closures. RASs have advantages, such as they are low cost and light weight, they require less energy to process, and they reduce emissions when used in vehicles. The hemming ability of RASs was investigated through various quenching rates and hot-rolling reduction rates. The hemming factor (HF) values of low Fe content samples (0.1 and 0.3 wt% Fe content) were 2 and 3. The hemming ability of samples with an Fe content of 0.5 wt% was unacceptable for applications to automotive outer closures (i.e., HF values of 4 and 5). The HF values changed from 3 to 5 for even higher Fe content samples (0.8 wt% Fe), depending on the quenching and hot-rolling reduction rates. Lower quenching (air quenching) and lower hot-rolling reduction rates (6-pass hot rolling) both improved the hemming ability of the high Fe content samples. A low-cost and recycle-friendly aluminum alloy automotive sheet from end-of-life vehicles is presented, and its hemming properties are characterized.Keywords Recycle-friendly · Lightweight · Hemming · Aluminum alloy · Automotive sheets · End-of-life vehicle Abbreviations
