RESUMO

Phase transformations and composition of Al-Fe-Si, Al-Co-Si and Al-Ni-Si based rapidly quenched ribbons have been investigated. Different Al-Si based alloys with varying Si content and additions of third metallic element, namely Al80Si20, Al60Si40, Al75Fe5Si20, Al70Fe10Si20, Al75Co5Si20, Al70Co10Si20, Al75Ni5Si20, Al70Ni10Si20 were analyzed. Variation of phase composition with elemental composition was observed. Evolution of phases was determined by resistometry, differential scanning calorimetry (DSC). In situ X-ray diffraction (XRD) and transmission electron microscope (TEM) records were observed during isothermal and isochronal annealing.
