【 摘 要 】

This paper presents a comparative study of the preparation and characterisation of Fe38.5Co38.5Nb7P15Cu1 alloy produced bymechanical alloying (MA) and rapid quenching (RQ) method. In order to obtain the starting mixture (SS) in the present study, weopted for the replacement of elemental Nb and P powders with ferroalloy powders of niobium and phosphorus. Benzene was usedas a control agent of the process (PCA) for wet MA. The samples obtained (powders and ribbons) were characterised by X-raydiffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), X-ray microanalysis (EDX),magnetic measurements M(H) and thermomagnetic measurements M(T). After 40 h of wet MA, the alloy was partially amorphous,and the ribbons obtained by RQ do not show an amorphous state. Also, the magnetic measurements show the influence of themethod used on the magnetic properties.
