摘要

Several homogenization treatments were applied in DC ingots of aluminum alloy AArn6063, in order to analyze the microstructures developed in the homogenizedrnconditions and their effects on the hot workability of this alloy. Microstructures of ascastrnsamples and samples homogenized in different conditions were analyzed byrnmeans of optical metallography, X-ray diffraction and in the scanning electronrnmicroscope (SEM with EDS). The changes in distribution and morphology of secondrnphase particles (AlFeSi and Mg2Si), due to the different homogenization treatments,rncould be assessed. Samples were selected for hot tensile testing, in temperaturesrnbetween 470 and 650oC, so that hot workability (here meaning hot ductility) could bernassessed in different conditions of strain rate. The homogenization treatmentsrnenabled the transformation of the undesirable intermetallic β-AlFeSi phase, which isrnpresent in the as-cast condition, to α-AlFeSi particles, which are not detrimental tornthe extrudability of the alloy. Hot tensile tests could show that homogenization canrnchange the hot ductility response of the alloy.
