Magnetic, microstructure characterization of Fe65Co35 nanocrystalline alloy synthesized by

mechanicalalloying process

S.Mebrek, A.Haddad, M.Zergoug, N.Haine

Abstract : An investigation was conducted to explore the applicability of magnetic and microwavetechniques to characterize grains size variation during mechanical alloying. A series ofNanocrystalline Fe65Co35 samples have been prepared, these structures are prepared usingmechanical alloying based on planetary ball mill under several milling conditions.Mechanical alloying is a non-equilibrium process for materials synthesis. The structuraleffects of mechanical alloying of powders were investigated by X - Ray diffractionanalysis, microwaves and VSM magnetic technique. Consequently, alloy powder with an180180average grain size about of 8 nm was obtained. Experimental results show that finenanocrystalline alloy powders prepared by mechanical milling are very promising formicrowave applications.

Keywords : Fe-Co powder; Mechanical alloying; Magnetic properties; Microwave.
