This paper presents the results of a comparison of two methods for the preparation of permalloy-type material. The nominal blend composition was Ni80-Fe14.7-Mo4.5-Mn0.5-Si0.3. Samples were prepared in the form of toroids using powder metallurgy and an induction casting method. The following measurements were carried out on samples: computer tomography, VSM, XRD, and measurement of the total magnetic losses at different frequencies and the magnetic induction. Both technologies were found to create a crystalline material with similar phases. The sample prepared by the induction casting method exhibited high coercivity, low magnetization saturation and high excess losses in comparison with the sample that had been subjected to a 24h and 120h milling duration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
