Original Abstract

80Ni-14.7Fe-4.4Mo-0.5Mn-0.3Si soft magnetic alloy of Permalloy type was prepared by mechanical alloying from atomic powders. The powders were mechanically alloyed by high-energy ball milling in a planetary mill in an air atmosphere. Comparing results from electron energy chemical analysis and X-ray diffraction analysis it was found that hardness of the alloy corresponds to the chemical and phase homogeneity of the composite powder. After 24 hours of milling, the single phase homogenous composite powder had the Vickers hardness of about 750 HV1 and coercivity about 40 A.m-1. Further alloying led to powder grain size and crystallinite size refinement. This process was accompanied by an increase in the defects amount and thus with increasing of coercivity, up to 120 A.m-1 after alloying for 120 hours.
