Magnetic, Microstructure Characterization of Fe65Co35 Nano Crystalline Alloy Synthesized by Mechanical Alloying Process

Abstract

An investigation was conducted to explore the applicability of magnetic and microwave techniques to characterize grains size variation during mechanical alloying. A series of Nano crystalline Fe65Co35samples have been prepared, these structures are prepared using mechanical alloying based on planetary ball mill under several milling conditions. Mechanical alloying is a non-equilibrium process for materials synthesis. The structural effects of mechanical alloying of powders were investigated by X-Ray diffraction analysis, microwaves and VSM magnetic technique. Consequently, alloy powder with an average grain size about of 8 nm was obtained. Experimental results show that fine Nano crystalline alloy powders prepared by mechanical milling are very promising for microwave applications.
