Abstract

Fe-based amorphous alloys have a high application potential due to their unique soft magnetic and mechanical properties, and high corrosion resistance. These alloys can be obtained in the final shape without making other processing operations, which makes them suitable for many electronic applications such as magnetic shielding, magnetic sensors, magnetic cores and other devices. Bulk Fe67Cr4Mo4Ga4P12B5C4 amorphous alloys in rods form with the diameter of 1 mm and 35 mm in length were successfully prepared by copper mould casting. The samples obtained were structural investigated by X-Ray diffraction (XRD), differential thermal analysis (DTA), and magnetic characterized by conventional low frequency induction method. The mechanical properties such as hardness and bulk modulus were determined using micro indentation tests by analysing the load-depth curve. This study was made in order to use these bulk amorphous alloys in magnetic shielding applications..
