Effects of Sm content on the phase structure, microstructure and magnetic properties of the Sm Zr0.2(Fe0·8Co0.2)11.5Ti0.5 (x=0.8–1.4) alloys

This paper refers to the structural and magnetic properties of [(Fe80Nb6B14)0.88Dy0.12]1−xZrx (x = 0; 0.01; 0.02; 0.05; 0.1; 0.2; 0.3; 0.5) alloys obtained by the vacuum mold suction casting method. The analysis of the phase contribution indicated a change in the compositions of the alloys. For x < 0.05, occurrence of the dominant Dy2Fe14B phase was observed, while a further increase in the Zr content led to the increasing contribution of the Fe–Zr compounds and, simultaneously, separation of crystalline Dy. The dilution of (Fe80Nb6B14)0.88Dy0.12 in Zr strongly influenced the magnetization processes of the examined alloys. Generally, with the increasing x parameter, we observed a decrease in coercivity; however, the unexpected increase in magnetic saturation and remanence for x = 0.2 and x = 0.3 was shown and discussed.

Microstructure And Magnetic Properties

Fe100-xCox-6.5wt%Si (x=0, 1, 3, 5, 7, 10, 15, 35, 50) magnetic powder cores (MPCs) were prepared by gas atomization,insulation, compression molding, and heat treatment. The effects of Co element on microstructure and magnetic properties of the Fe-6.5wt%Si MPCs were investigated. The results showed that the addition of Co element doesn’t change the phase structure of Fe-6.5wt%Si alloy powders. The saturation magnetization of the powders decreased after the first increase with the increase of the Co content, reaching the maximumfor Fe90Co10-6.5wt%Sipowder sample.The saturation magnetization of the MPCs decreased after the first increase with the increase of the Co content, reaching the maximumfor Fe93Co7-6.5wt%Si sample.The effective permeability of the MPCsdecreased after the first increase with the increase of the Co content, reaching the maximum for Fe95Co5-6.5wt%SiMPCs. The core loss of the MPCsincreased after the first decrease with the increase of the Co content, reaching the minimumfor Fe97Co3-6.5wt%SiMPCs. A small amount of Co element can improve effectively the whole magnetic properties of the Fe-6.5wt%Si MPCs.
