We developed the EPMA mapping method of small α-AlFeSi(Al8.3Fe2Si) and β-AlFeSi(Al8.9Fe2Si2) particles in the billets of Al-Mg-Si alloys such as AA6063 alloys. To discriminate between α-AlFeSi and β-AlFeSi particles we used the relative X-ray intensities of Fe/Si ratio, the I Fe/I Si ratio, instead of the Fe/Si mass ratio. To obtain the I Fe/I Si ratio, we used a Monte Carlo method. In

The phase transformation of β-AlFeSi to α-Al(FeMn)Si is an important process during the homogenisation of as-cast AA 6xxx aluminium alloys. During this homogenisation process, at temperatures between 530 and 600 °C [1] , plate-like monoclinic intermetallic β-Al 5 FeSi particles transform to more globular cubic α-Al 12 (Fe x Mn (1− x
Fig. 2b and c shows that β-AlFeSi phase has been removed of the microstructure of the alloys 2 and 3. Table 3 shows the quantification of α-AlFeSi, α-pos-dendritic AlFeSi in the form of Chinese script, β-AlFeSi and Si and it can be observed that α-AlFeSi and Si is decreased in alloy 2 and increased in alloy 3 doing a comparative with alloy

\\(\\beta \\)-AlFeSi is of particular interest as it is generally considered to be detrimental and forms in facetted, planar morphologies that promote strain inhomogeneity and reduce tensile ductility and toughness.[4,5] \\(\\beta \\)-AlFeSi may also promote the nucleation of Al-Si eutectic in higher Si concentration casting alloys.[] Although postsolidification homogenization treatments are used to
