Abstract
This study aims to investigate the dependence of phase composition, structural/microstructural parameters, and the magnetic properties as function of milling time of Fe9Cu2Zn powder mixture. X-ray diffraction analysis indicated that the milled powder crystallizes in the fcc alpha-Cu5Zn3, cubic complex Gamma-Fe4Zn9, and trigonal alpha-Cu3Zn structures embedded within bcc alpha-Fe solid solution. The magnetization curves infer that the alloy presents stable magnetic properties (coercivity, squareness ratio, nucleation field, hysteresis loss energy, magnetic permeability) after 1 h of milling. The coercive field evolution has been found to be related to the evolution of crystallite size and the microstrain of the alloy.
