  • Structural Analysis and Magnetic Properties of FeCo Alloys ...

    Abstract. A systematic study on the structural and magnetic properties of alloys (, in wt. percent) obtained by mechanical alloying is presented. Elemental powders of Fe and Co mixed in an adequate weight ratio were milled at room temperature in a shaker mixer mill using vials and balls of hardened steel as milling media with a ball : powder weight ratio of 12 : 1.
