“…Moreover, spherical particles of aluminium boride can be seen on the surface of the sheets. They are small in size and non-deformable particles compared to the ductile aluminium matrix, but they can affect the performance of the sheet rolling [19,20].…”

“…They are small in size and non-deformable particles compared to the ductile aluminium matrix, but they can affect the performance of the sheet rolling. [19,20] Homogenization processing has a critical contribution by allowing the precipitation of excessive alloying elements in the solid solution before subsequent thermomechanical processing. However, the high solidification rate encountered in TRC (twin-roll casting) not only favours the supersaturation and metastable condition of the alloying elements, but also hinders their microsegregation.…”

The industrial production of products, such as foil and aluminium alloy strips, begins with the production of semi-finished products in the form of slabs. These are produced by the continuous casting process, which is quick and does not allow the equilibrium conditions of solidification. Non-homogeneity—such as micro and macro segregation, non-equilibrium phases and microstructural constituents, as well as stresses arising during non-equilibrium solidification—are eliminated by means of homogenization annealing. In this way, a number of technological difficulties in the further processing of semi-finished products can be avoided. The aim of this research was the optimization of the homogenization annealing of the EN AW 8006 alloy. With the Thermo-Calc software, a thermodynamic simulation of equilibrium and non-equilibrium solidification was performed. Differential scanning calorimetry (DSC) was performed on selected samples in as-cast state and after various regimes of homogenization annealing and was used for the simulation of homogenization annealing. Using an optical microscope (OM), a scanning electron microscope (SEM) and an energy dispersion spectrometer (EDS), the microstructure of the samples was examined. Based on the results, it was concluded that homogenization annealing has already taken place after 8 h at 580 °C to the extent, that the material is then suitable for further processing.

“…For instance, the AA8XXX alloy series is an interesting category of aluminum alloys which includes additions of iron and manganese close to the Al-Fe-Mn ternary eutectic [32]. This provides an excellent combination of strength and ductility at room temperature, and allows the mechanical strength to be maintained at elevated temperatures [32,33]. In particular, AA8006 is a well-known alloy in this series which is characterized by intermediate strength with high ductility, and contains approximately ~1.5 wt% and ~0.5 wt%, contents of iron and manganese, respectively [32].…”

“…The desirable tensile properties are attained through a uniform dispersion of fine stabilized secondary-phase dispersoids within a fine-grained Al-matrix [33]. This aluminum alloy is typically processed in the form of common household Al-foils in wide-spread use in containers, heat exchangers, air-conditioners, insulations, cable wrap and other technical applications [32,33]. However, general applications of these Al-based materials are restricted due to their low hardness, strength and wear resistance [31].…”

“…As ligas de alumínio da série 8XXX são caracterizadas por composições variadas, sendo as mais importantes: as denominadas 8006 (Al-Fe-Mn), 8011 (Al-Fe-Si) e 8018 (Al-Fe-Si-Cu) [13]. Estas ligas têm sido utilizadas com sucesso pelas indústrias de embalagem e microeletrônica, devido à sua alta ductilidade.…”
