    Abstract:

    In a previous work1, the glass forming ability and the atomic structure of the Al-rich Al-Fe-Nb amorphous alloys have been analysed. The aim of this work is to study the crystallisation behaviour of these systems, mainly using differential scanning calorimetry. These amorphous alloys present high thermal stability and their crystallisation process takes places in two stages at quite different temperatures, the first stage corresponds to α-Al crystallisation. The apparent activation energy and the transformation diagrams are determined, and the mechanisms that control the crystallisation are discussed.
