Abstract
The necessity of obtaining amorphous alloys with higher thickness which correspond to different industrial applications requirements, determined the intensification of researchers regarding the processing possibility of some amorphous alloys characterized by critical cooling rate as small as possible. Consequently, the focus of this paper was to process ferromagnetic bulk amorphous alloy rods, with 1 and 2 mm diameter, using copper mould casting method. The samples obtained were structural investigated by X-Ray diffraction (XRD), differential thermal analysis (DTA), differential scanning calorimetry (DSC) and magnetic characterized by conventional low frequency induction method, in order to observe the influence of the elaboration technology on glass forming ability and magnetic properties of the elaborated alloy.
