dc.description.abstract | The crystallization process, both at the initial and subsequent stages, of amorphous
Al88-RE4-Ni8 alloys (RE = Y, Sm and Ce) has been studied. Additionally, the consequences of adding
1 at.% Cu replacing Ni or Al were studied. The stability of the amorphous structure in melt spun
ribbons was thermally studied by di erential scanning calorimetry, with Ce alloys being the most
stable. The e ect of Cu to reduce the nanocrystal size during primary crystallization was analyzed by
transmission electron microscopy. This latter technique and x-ray di raction showed the formation
of intermetallic phases at higher temperatures. A clear di erence was observed for the Ce alloy,
with a simpler sequence involving the presence of Al3Ni and Al11Ce3. However, for the Y and Sm
alloys, a more complex evolution involving metastable ternary phases before Al19RE5Ni3 appears,
takes place. The shape of the intermetallics changes from equiaxial in the Ce alloys to elongate for Y
and Sm, with longer particles for Sm and, in general, when Cu is added to the alloy. | es |
